test(handlers): add PatchAbilities regression coverage

Adds 10 test cases for PATCH /workspaces/:id/abilities:

Happy path:
- broadcast_enabled=true → 200
- broadcast_enabled=false → 200
- talk_to_user_enabled=true → 200
- both fields in one request → 200 (each UPDATE in order)

Input validation:
- empty body {} → 400
- non-JSON body → 400
- non-UUID workspace ID → 400

Database errors:
- workspace not found → 404
- DB error on existence check → 500
- DB error on broadcast_enabled UPDATE → 500
- DB error on talk_to_user_enabled UPDATE → 500

Covers workspace_abilities.go which was the only unreviewed handler
with zero test coverage. No production code changed.
