fix(mobile): replace 404 media library error with session-required state and device gallery fallback

The Postiz public API v1 does not expose a media listing endpoint.
Switch URL to the correct internal path (/media?page=0&search=), handle
the resulting 401 with a dedicated lock-icon state, and wire the existing
device gallery picker as an onPickFromDevice fallback so the modal stays
usable.
