[pull] master from supabase:master - #1120

## Summary

This is a precursor to unifying "compute and disk" and "infrastructure
pages". First step is just updating the existing compute and disk page
to make use of standard page and form patterns.

- Reorganizes the existing Compute and Disk form into the established
settings layout pattern, with Scaling, Compute, Disk, and Advanced
sections.
- Moves billing deltas to section headers while retaining the sticky
review footer.
- Adds animated notices, validation-error scrolling, and a responsive
compute-size selector (2 columns by default, 3 from 680px, and 4 from
900px).
- Preserves permissions, entitlements, cooldowns, read-only warnings,
replica pricing, GP3 validation, Nano/PITR locks, and the free Micro
upgrade treatment.
- Keeps the redesigned experience on `/settings/compute-and-disk` so it
can be reviewed independently of the route cutover.

## Stack

1. #48368 (this PR)
2. #48369
3. #48370

## How to test

1. Check out `chore/infra-compute-1-config` and start Studio with `pnpm
dev:studio`.
2. Open `/project/<ref>/settings/compute-and-disk`.
3. Confirm the page header and Scaling, Compute, Disk, and Advanced
sections follow the standard settings-page spacing, with the plan notice
directly below the Scaling header.
4. Change the compute size and disk configuration. Confirm billing
deltas appear in the relevant section headers and the sticky review
footer summarizes and applies the pending changes.
5. Enter invalid GP3 IOPS or throughput values and submit. Confirm the
validation message is shown and the first invalid field is scrolled into
view.
6. Exercise representative project states: insufficient permissions,
read-only mode, resize cooldown, Nano with PITR, a project with read
replicas, and a free Micro upgrade. Confirm the existing locks,
warnings, pricing, and upgrade treatment remain intact.
7. Resize the viewport and confirm the compute cards use 2 columns by
default, 3 columns from 680px, and no more than 4 columns from 900px.

- Improved billing change badges to reflect accurate before/after
totals.
- **Bug Fixes**
  - Fixed disk IOPS/throughput pricing to include replica-based charges.
- Strengthened disk sizing validation (GP3 limits, legacy/size edge
cases, spend-cap behavior, and provider-specific constraints).
