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)

## What kind of change does this PR introduce?
This is a prototype for private apps UI. There are no endpoints at the
minute, just wanted to see what a potential flow could look like.
