test(handlers): add coverage for PatchAbilities (workspace_abilities.go)

Add 9 tests for the PATCH /workspaces/:id/abilities handler — the only
exported function in workspace_abilities.go with zero prior coverage:

  - Invalid workspace ID → 400
  - Empty body (both fields nil) → 400
  - Malformed JSON → 400
  - Workspace not found (sql.ErrNoRows) → 404
  - Workspace DB error → 500/404 (short-circuit on err || !exists)
  - Update broadcast_enabled=true → 200
  - Update talk_to_user_enabled=true → 200
  - Update both abilities → 200
  - Update broadcast_enabled=false → 200

Uses sqlmock for the DB layer. The handler is a plain package-level
function (not a struct method) so no handler injection needed.

- * Companion to statusDotClass.test.ts (which covers statusDotClass's dot field
