Updates the dashboard disk-management copy to match the new AWS EBS
modification limits (already reflected in the docs): from the old fixed
"4-hour cooldown / once every 4 hours" framing to "up to 4 modifications
within a rolling 24-hour window".
This is a copy-only change plus one small logic-constant alignment.
Timer/countdown behavior is unchanged — this only updates wording to
bring the dashboard in line with the docs.
**Changed:**
- `DiskSpaceBar` autoscaling tooltip, `DiskCountdownRadial` card,
`DiskSizeConfiguration` "Importing a lot of data?" alert,
`DiskSizeConfigurationModal` alert title + both countdown branches,
`DiskManagementReviewAndSubmitDialog` IOPS + disk-size row descriptions,
and two code comments — all reworded to the new "4 per rolling 24-hour
window" framing
- `DiskSizeConfigurationModal` countdown now derives from the shared
`COOLDOWN_DURATION` constant (4h) instead of a stale hardcoded `6 * 60`
(6h), so the legacy resize path matches the newer disk-attributes path
## To test
- Open a Pro AWS project → **Settings → Compute and Disk** → hover the
**Autoscaling** pill on the disk bar: tooltip should read "…limited to 4
within a rolling 24-hour window" (no "once every 4 hours")
- Change IOPS only → **Review changes** → IOPS row description shows the
new "rolling 24-hour window… as soon as the previous one completes" copy
- Change disk size → **Review changes** → Disk size row shows "You can
modify disk attributes up to 4 times within a rolling 24-hour window"
(not "For 4 hours after changes…")
- On a non-AWS Pro project → **Database → Settings → Increase disk
size**: modal title reads "Disk modifications are limited to 4 per
rolling 24-hour window"; any "resize again in ~X" countdown is bounded
by 4 hours, not 6
- Sanity: none of the old "4-hour cooldown" / "once every 4 hours"
strings appear anywhere in the disk UI

## Summary by CodeRabbit
* **Bug Fixes**
* Updated disk resizing messages across the app to reflect a rolling
24-hour limit instead of a fixed 4-hour cooldown.
* Clarified when disk size, IOPS, and throughput changes are available
again, including more accurate next-available timing.
* Improved warning copy in disk configuration and review dialogs so
limit messages are consistent and easier to understand.

Add a warning that resizes may take additional time if they touch an
instance size < large.

## Summary by CodeRabbit
* **New Features**
* Added an additional warning in the disk management review dialog when
a resize may require extra downtime.
* The dialog now highlights higher-risk resize changes before
submission, helping users make more informed decisions.

file.
YES
## What kind of change does this PR introduce?
When a user selects IO2 on compute upgrade, the `0/MB` isn't quite
correct, whilst the costa delta of $0 is correct. We will hide the row
as it adds noise.

## Summary by CodeRabbit
* **Bug Fixes**
* Fixed disk management UI to correctly display the throughput
configuration row only when selecting GP3 storage type, ensuring the
interface accurately reflects available options for the selected storage
type.

[CONTRIBUTING.md](https://github.com/supabase/supabase/blob/master/CONTRIBUTING.md)

YES
## What kind of change does this PR introduce?
This takes our dialog to review compute upgrade's and gives it a bit
more visual clarity (as it can get confusing). Simplification and clear
communication of what differences there are.
