refactor(databases): remove DocumentsDB collection usage page

[lohanidamodar]

What

Removes the DocumentsDB collection usage page and its command-center Go to usage entry.

Why

The per-service DocumentsDB (and VectorsDB) /usage endpoints were removed in cloud — appwrite-labs/cloud#4679 ("chore(databases): remove per-service /usage endpoints", merged 2026-07-08) — because they duplicated the org/project usage surface. The console's collection usage page was the only consumer of the now-deleted documentsDB.getCollectionUsage, so calling it against any post-#4679 server 404s / breaks the type-check once the SDK is bumped.

Scope

• Deleted database-[database]/collection-[collection]/usage/[[period]]/ (+page.svelte, +page.ts)
• Removed the Go to usage command from the collection +layout.svelte

Unaffected (retained endpoints): the database, table, and project usage pages all use tablesDB.* (listUsage, getUsage, getTableUsage). The shared Usage view component stays (still used by the table usage page). Note: DocumentsDB is gated behind the multi-db feature flag, so this page was only reachable for opted-in accounts.

Verification

bun run check → 0 errors (88 pre-existing warnings unchanged). Prettier clean; ESLint 0 errors.

Greptile Summary

This PR removes the DocumentsDB collection usage page and its command-center shortcut following the removal of the /usage endpoints on the server side. The three changed files handle the deletion cleanly, but header.svelte — which was not included in the diff — still contains a "Usage" navigation tab pointing to the now-deleted route.

• +page.svelte and +page.ts under usage/[[period]]/ are deleted, removing the page component and its documentsDB.getCollectionUsage load call.
• The "Go to usage" keyboard shortcut is removed from +layout.svelte.
• header.svelte (unchanged in this PR) still renders a "Usage" tab that links to ${path}/usage, which will 404 for all collection pages accessible to multi-db users.

Confidence Score: 3/5

The route deletion is incomplete — the Usage tab in the collection header still navigates to the deleted page, leaving a broken tab visible to all multi-db users.

The keyboard shortcut and route files are cleaned up correctly, but header.svelte was not updated. Every collection header rendered for multi-db users will show a Usage tab that resolves to a missing route. The fix is a small, isolated deletion in header.svelte.

src/routes/(console)/project-[region]-[project]/databases/database-[database]/collection-[collection]/header.svelte — the Usage tab entry needs to be removed.

Important Files Changed

src/routes/(console)/project-[region]-[project]/databases/database-[database]/collection-[collection]/usage/[[period]]/+page.svelte	Deleted correctly — the Svelte page component that rendered the DocumentsDB collection usage view is removed.
src/routes/(console)/project-[region]-[project]/databases/database-[database]/collection-[collection]/usage/[[period]]/+page.ts	Deleted correctly — the load function calling the now-removed documentsDB.getCollectionUsage endpoint is removed.
