fix(handlers): make PatchAbilities atomic when both fields supplied (#2131)

Previously PatchAbilities applied broadcast_enabled and
talk_to_user_enabled with two separate UPDATE statements. If the first
succeeded and the second failed, the workspace was left in a partial/
ambiguous capability state.

When both fields are present in the PATCH body, apply them in a single
combined UPDATE so the mutation is all-or-nothing. Single-field updates
continue to use the original per-column statements.

Updates the existing BothFields test to expect one combined UPDATE, and
replaces the old BothFields_BroadcastFails test with
BothFields_UpdateError which validates the atomic path.

Fixes #2131
