feat(gateway): add BlueBubbles iMessage platform adapter (#6437)
Adds Apple iMessage as a gateway platform via BlueBubbles macOS server.

Architecture:
- Webhook-based inbound (event-driven, no polling/dedup needed)
- Email/phone → chat GUID resolution for user-friendly addressing
- Private API safety (checks helper_connected before tapback/typing)
- Inbound attachment downloading (images, audio, documents cached locally)
- Markdown stripping for clean iMessage delivery
- Smart progress suppression for platforms without message editing

Based on PR #5869 by @benjaminsehl (webhook architecture, GUID resolution,
Private API safety, progress suppression) with inbound attachment downloading
from PR #4588 by @1960697431 (attachment cache routing).

Integration points: Platform enum, env config, adapter factory, auth maps,
cron delivery, send_message routing, channel directory, platform hints,
toolset definition, setup wizard, status display.

27 tests covering config, adapter, webhook parsing, GUID resolution,
attachment download routing, toolset consistency, and prompt hints.

"""BlueBubbles iMessage platform adapter.
Uses the local BlueBubbles macOS server for outbound REST sends and inbound
webhooks. Supports text messaging, media attachments (images, voice, video,
documents), tapback reactions, typing indicators, and read receipts.
Architecture based on PR #5869 (benjaminsehl) with inbound attachment
downloading from PR #4588 (YuhangLin).
