test(cua): fix #39/#42 deterministic assertions to match real app behavior

#39 (backgrounded permission notification):
- Event is permission.asked, not permission.requested (events.ts already calls
  notify() for it; send() only fires while backgrounded).
- Assert on APP_PACKAGE (the only token guaranteed in every dumpsys record) plus
  the actual copy ('Permission requested' / 'A tool needs your approval') instead
  of the non-existent 'Agent needs approval' string.

#42 (SSE disconnect banner):
- reconnectAttempts only zeroes after STABLE_CONNECTION_MS (10s) past a healthy
  reconnect, and the pending backoff timer can take up to 15s — so the banner can
  linger ~25s. Poll up to 40s for dismissal instead of a fixed 15s sleep to avoid
  a false 'still showing' failure.
