fix: resolve 7 failing CI tests (#3936)

1. matrix voice: _on_room_message_media unconditionally overwrote
   media_urls with the image cache path (always None for non-images),
   wiping the locally-cached voice path. Now only overrides when
   cached_path is truthy.

2. cli_tools_command: /tools disable no longer prompts for confirmation
   (input() removed in earlier commit to fix TUI hang), but tests still
   expected the old Y/N prompt flow. Updated tests to match current
   behavior (direct apply + session reset).

3. slack app_mention: connect() was refactored for multi-workspace
   (creates AsyncWebClient per token), but test only mocked the old
   self._app.client path. Added AsyncWebClient and acquire_scoped_lock
   mocks.

4. website_policy: module-level _cached_policy from earlier tests caused
   fast-path return of None. Added invalidate_cache() before assertion.

5. codex 401 refresh: already passing on current main (fixed by
   intervening commit).
