feat(mobile): show warehouse-backed sources in inbox Source filter

Port PostHog/code #3597 to mobile: the inbox Source filter and signal cards
only handled ~9 native products, so signals from warehouse-backed sources
(Stripe, Sentry, Zendesk, etc.) could not be filtered by source and rendered
with a crude fallback label and no icon.

- Derive the Source filter's warehouse entries from the shared
  EXTERNAL_INBOX_SOURCES registry instead of a hardcoded list.
- Give warehouse sources a registry label and a generic Plug icon fallback in
  SignalCard (no per-source mobile icon assets, matching desktop's PlugIcon
  fallback).
- Re-export the shared SourceProduct union from the mobile filter store so the
  wider set typechecks.
- Move the pure sourceLine helper into the inbox utils and cover it, the
  widened source filter, and the derived options list with tests.
