## Context
Realised that tooltips were not showing up for supavisor charts in
database reports - just needed to flip a boolean
Although - i don't have any projects with supavisor connections data
(even on prod) so I can't visually verify this atm
Also fixes a small issue in which docs url for the chart wasn't showing
if the chart had no data, e.g:
<img width="996" height="311" alt="image"
src="https://github.com/user-attachments/assets/926febe4-9e3d-4975-9278-e7582d6ae12d"
/>
Should have docs button like this
<img width="949" height="351" alt="image"
src="https://github.com/user-attachments/assets/7561c1c5-94ae-405b-bd54-6bc94be0dd0a"
/>

## Summary by CodeRabbit
* **New Features**
* Enabled tooltips for the “Shared Pooler (Supavisor) client
connections” chart so the metric can be inspected directly.
* **UI Improvements**
* Adjusted the tooltip positioning in the chart header for clearer
readability.
* When charts have no data, the “Learn more”/documentation link now
follows the provided docs URL.

## Problem
Our `<Button>` component breaks the default `button` contract by
redefining the `type` prop to set its variant (`primary`, `default`,
etc) instead of the button type (`submit`, `button`, etc).
This is confusing and forces to write more code when using it with
shadcn components that expect/inject the standard button props.
## Solution
- rename the `type` prop to `variant`
- rename the `htmlType` prop to `type`
- propagate the changes where necessary
- format code
## How to test
As this is just prop renaming, if it builds it's ok

Fixes [DEBUG-94](https://linear.app/supabase/issue/DEBUG-94)
## Summary
- **Min MB units**: Added \`formatBytesMinMB\` helper that always
formats byte values in at least MB. Applied to RAM and swap y-axis tick
formatters, tooltips, and chart headers.
- **Swap chart scale**: Every Supabase compute instance is provisioned
with **1 GB of swap regardless of size** (per
[docs](https://supabase.com/docs/guides/troubleshooting/memory-and-swap-usage-explained-aPNgm0)),
so the swap y-axis always shows at least 0 to 1 GB. Low swap usage no
longer fills the full chart height. Removed the show/hide limit toggle
since the limit is implicit in the y-axis scale.
- **Swap units in header/tooltip**: Fixed all three formatters (initial
header, hover-sync header, tooltip) to use \`formatBytesMinMB\` for swap
so the value always shows a unit like "2.00 MB".
- **Reference-line defensive fix**: Added a \`customValue\` fallback in
\`useAttributeQueries\` so future reference-line attributes that use
\`customValue\` instead of \`value\` are not silently overwritten to 0.
## Test plan
- [ ] Open DB Reports and verify RAM/Swap y-axis labels show MB (or GB
for large values), never KB or bytes
- [ ] Hover a bar in the swap chart and verify tooltip and header show
the same value with a unit (e.g. "2.00 MB")
- [ ] With low or zero swap usage, the chart bars are flat and the
y-axis goes 0 to 1 GB
- [ ] CPU chart limit toggle still renders at 100% (regression check on
the \`useAttributeQueries\` fallback change)

## Problem
When users hit a disk IO exhaustion notification, they open the Database
Observability report and find IOPS and throughput charts, but no view of
the metric that actually fired the warning: the EBS burst credit
balance. That signal is currently only available behind Custom Reports,
so the warning feels disconnected from the visible data.
> "The Dashboard actually shows them their burst budget, not their
normal disk usage. It leads to a lot of confusion." — support
> "Customers may receive an 'exhausting multiple resources' warning and
it's confusing because all the charts are 'fine', but it's the burst
credits exhaustion that fails them." — Maksym
Reported in [Linear
DEBUG-60](https://linear.app/supabase/issue/DEBUG-60).
## Fix
Add a clearly-labeled "Disk IO Burst Balance" chart to
[getReportAttributesV2](apps/studio/data/reports/database-charts.ts)
plotting `disk_io_budget` (% remaining) on a 0-100 axis. Tooltip and
titleTooltip explain the 5 MB/s throttle floor so users can correlate
this chart with the exhaustion banner copy (also being updated in
[supabase#45514](https://github.com/supabase/supabase/pull/45514)).
The chart is hidden for compute variants that have dedicated I/O
resources (4XL and above) since the burst credit pool does not apply
there. Burstable variants (nano through 2XL) see the chart inline next
to the existing IOPS and throughput charts.
DEBUG-61 ("replace Disk IO Usage % chart with disk throughput") was
already addressed in the V2 migration (the report only renders
`disk-iops` and `disk-throughput`; the old burst-percentage chart is
gone). I'll close that issue as completed once this lands.
## Test plan
- [ ] Visit `/project/{ref}/observability/database` on a project running
`nano`/`micro`/`small`/`medium`/`large`/`xlarge`/`2xlarge` compute.
Confirm the new "Disk IO Burst Balance" chart appears between throughput
and connections.
- [ ] On a project running `4xlarge` or larger compute, confirm the
chart is hidden (chart is omitted by `hide: !hasBurstableIO`).
- [ ] Hover the chart and a data point. Confirm the title tooltip and
inline attribute tooltip both surface the 5 MB/s throttle behaviour.
- [ ] Series renders 0-100 on the Y-axis.

## Summary by CodeRabbit
* **New Features**
* Added a Disk IO Burst Balance chart to monitor remaining burst
credits; displays percentage (0–100%) with tooltip referencing baseline
throughput. Shown only for supported compute variants and when the
feature flag is enabled.
* **Bug Fixes / UI Improvements**
* Improved chart header tooltip presentation: uses a unified tooltip,
includes inline docs links when available, and avoids duplicate docs
icons.

## Problem
The dashboard's timezone picker (#45517) propagates to log timestamps
and the shared TimestampInfo component, but observability and reports
charts still render their X-axis labels, range labels, and tooltip
headers in the browser's local timezone. The result is jarring once a
user picks a non-local timezone: hover a chart and you get one tz, hover
a log row and you get another.
## Fix
Routes all display-side timestamp formatting in the chart layer through
the existing picker-aware helpers (\`useFormatDateTime\` /
\`formatDateTime\`) so chart UI matches the rest of the dashboard.
- **ComposedChart.utils** \`CustomTooltip\` (the hotspot — drives every
observability dashboard tooltip): reads the active timezone via
\`useTimezone\` for both the header label and the formatted timestamp.
- **AreaChart** / **BarChart**: introduce a \`formatChartDate\` helper
that honours each component's existing \`displayDateInUtc\` prop,
otherwise routes through the picker.
- **ChartBlock**: the two recharts \`labelFormatter\` arrows now close
over \`useFormatDateTime\`.
- **ChartHighlightActions**: range labels in the zoom dropdown migrated
to the same hook.
Intentionally untouched (must stay UTC):
- \`ChartHandler\` / \`ChartBlock\` \`startDate\`/\`endDate\` (API range
params, day boundary).
- \`ChartBlock.tsx:166\` explicit \`.utc()\` data-key normalisation.
- \`useFillTimeseriesSorted\` and friends (range math, no display).
## How to test
- Sign in. Open the avatar dropdown, pick a timezone different from your
browser local (e.g. Asia/Tokyo).
- Visit any project, then \`/project/<ref>/reports/database\` (or any
\`/observability/...\` page).
- Hover any chart series — the tooltip header should display the chosen
IANA name and times in that timezone.
- Click-drag a range on a chart to open the zoom dropdown — start/end
labels in the menu should also be in the chosen timezone.
- Switch back to "Auto detect" and confirm everything reverts to
browser-local.
- For an AreaChart/BarChart that uses \`displayDateInUtc\` (e.g. some
legacy reports), confirm those still render in UTC regardless of picker.

## Summary by CodeRabbit
* **Refactor**
* Standardized date/time formatting across charts, tooltips, axis
labels, header/footer labels, and highlight range labels in Reports and
chart components.
* Switched to a shared, timezone-aware formatter that respects UTC
display mode or the selected picker/timezone, ensuring consistent,
human-readable timestamps throughout the UI.

This PR preps the monorepo for a migration to Tailwind v4:
- Bump all Tailwind dependencies and libraries to the latest possible
version, while still compatible with Tailwind 3.
- Cleans up obsolete Tailwind 3 specific options and configs.
- Cleans up unused CSS files and fixes the CSS imports.
- Migrates all `important` uses in `@apply` lines to using the `!`
prefix.
- Move `typography.css` to the `config` package and import it from the
apps.
- Migrated all occurrences of `flex-grow`, `flex-shrink`,
`overflow-clip` and `overflow-ellipsis` since they're deprecated and
will be removed in Tailwind 4.
- Make the default theme object typesafe in the `ui` package.
- Migrate all `bg-opacity`, `border-opacity`, `ring-opacity` and
`divider-opacity` to the new format where they're declared as part of
the property color.
- Bump and unify all imports of `postcss` dependency.
