Removes Studio code that nothing imports, as reported by knip. First PR
in a stack of three: this one is pure deletions, #49720 removes the
unused dependencies, #49721 upgrades knip and adds the CI gate so this
doesn't accumulate again.
Every file was verified with a repo-wide grep for its basename, exported
symbols, and string/dynamic imports before deletion — none are reachable
via `next/dynamic`, a barrel file, or a config.
**Removed:**
-
`Billing/Usage/UsageWarningAlerts/{CPU,RAM,DiskIOBandwidth}Warnings.tsx`
(whole directory)
- `DataWarehouse/FormFooterChangeBadge.tsx` (whole directory)
- `Database/Replication/ReplicationDiagram/EmptyReplicationDiagram.tsx`
- `Integrations/Vercel/OrganizationPicker.tsx`
- `QueryInsights/QueryInsightsTable/QueryInsightsTableRow.tsx`
- `hooks/misc/useTrackExperimentExposure.ts`
- `data/ai/{parse-client-code,sql-policy}-mutation.ts`,
`data/misc/parse-query-mutation.ts`,
`data/database/table-check-rls-mutation.ts`
-
`data/notifications/notifications-v2-{archive-all-mutation,summary-query}.ts`
+ their two now-unused keys in `notifications/keys.ts` (`listV2` kept)
-
`data/platform-apps/platform-app-{update,signing-key-delete}-mutation.ts`
- `DateTimeFormats.DATE_ONLY` and the unused
`Notebooks.{MarkdownCell,LogCell,ChartConfig}` types
**Changed:**
- `ReportPadding` no longer has a duplicate default export; its 9
default importers (observability pages) now use the named export
Not removed: `CONSTRAINT_TYPE`'s unused members mirror the closed set of
`pg_constraint.contype` values, so they're documentation rather than
dead code — suppressed narrowly in #49721's knip config instead.
## To test
- `pnpm --filter studio run typecheck` and `lint:ratchet` pass
- Observability pages (`/project/[ref]/observability/*`) still render
with padding — they're the only code touched, via the `ReportPadding`
import change
- Notifications popover still loads and marks-as-read (the removed keys
weren't used for invalidation)

## Context
Building on top of "Database Connections" - this adds a top summary
section, again from `pg_stat_activity`

/>
Each block comes with a tooltip in hopes to educate the significance of
each metric
- Connections: Spread of connections per database role
<img width="313" height="164" alt="image"
src="https://github.com/user-attachments/assets/8ceeab5d-b960-4be3-9a5b-8600bd5cf303"
/>
- Active queries: Rough representative of activity
<img width="350" height="196" alt="image"
src="https://github.com/user-attachments/assets/f9705ff1-a869-409a-86b6-50170a169674"
/>
- Idle in transaction: Important to identify as this indicates locks
(Suggests root cause)
<img width="350" height="196" alt="image"
src="https://github.com/user-attachments/assets/f9705ff1-a869-409a-86b6-50170a169674"
/>
- Blocked queries: Also important to identify stuck queries
<img width="335" height="183" alt="image"
src="https://github.com/user-attachments/assets/57255fb8-24f6-4ddd-aa54-850a77173b5c"
/>
- Longest running query: Might be useful to identify unusually long
queries
- Will be `text-warning` if exceeds 30 seconds for active queries,
`text-destructive` if exceeds 10 seconds for queries idle in transaction
<img width="342" height="119" alt="image"
src="https://github.com/user-attachments/assets/f6783b43-058a-4a32-a40c-0bc64f23d2ce"
/>
"Summarize activity" CTA leverages on the Assistant to give a quick
overview - highlights any potential issues for quick reference

src="https://github.com/user-attachments/assets/340121fe-3186-48a5-8023-fbac2a93397a"
/>
## Other changes
- Hides "View running queries" in SQL Editor if `topForPostgres` feature
flag is enabled (since this UI is meant to replace that)

content for metric labels.

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.
