[HarshMN2345]

Summary

• Follow-up to fix(databases): remove leftover top-level Usage tab #3128: removes the per-table Usage tab (table-[table]/usage), which calls tablesDB.getTableUsage() — an endpoint being dropped along with the backend usage-endpoint removal, and already showing no useful data on cloud.

• Table page no longer shows a Usage tab

Stale Usage Command Route

The table Usage tab and page are removed here, but the table layout still registers a command-palette action that navigates to withPath(basePath, '/usage'). A user can still trigger that action from any table page and land on the now-deleted route, showing a client-side 404.

**Stale Usage Command Route**

The table Usage tab and page are removed here, but the table layout still registers a command-palette action that navigates to `withPath(basePath, '/usage')`. A user can still trigger that action from any table page and land on the now-deleted route, showing a client-side 404.
