fix(offline): allow playback controls without API client init

pause, resume, stop, seek, and volume commands required
RequiresClientInit which fails when offline (no internet = no bundle
extraction = client not initialized). These commands only use the
local Player/CoreBridge, not the Qobuz API client.

Changed to RequiresUserSession which passes in offline mode since
the offline session activates from cached user data.

Fixes #173
