* feat(ios): read-only offline cache for chat sessions and transcripts

Cache-first cold open for the iOS chat tab: the last known transcript and
session list render immediately from a local SQLite cache, then live gateway
history replaces them wholesale through the existing reconciliation path.
When the gateway is unreachable, recent sessions and transcripts stay
browsable read-only; sending remains gated by the existing connection state.

- New OpenClawChatTranscriptCache protocol seam plus SQLite-backed store in
  OpenClawChatUI (raw SQLite3, no new dependencies), scoped per gateway
  stableID so transcripts never leak across paired gateways.
- Bounds: 50 sessions, 50 transcripts, 200 messages per session; text rows
  only (attachment/binary payloads and tool arguments are stripped).
- Disposable cache: schema versioned via user_version; any open/schema/decode
  mismatch drops and rebuilds silently. File protection
  completeUntilFirstUserAuthentication on iOS.
- View model pre-paints from cache only until a live response applies
  (hasAppliedLiveHistory/hasAppliedLiveSessions guards); write-through is
  chained and off the render path.
- iOS wiring keys the chat view model identity on transport mode plus cache
  gateway ID so switching paired gateways rebuilds the view model.
