feat(pancake): add TikTok sub-platform support (#990)

Add TikTok account type dropdown (Livestream AIO, Business Messaging,
TikTok Shop) to Pancake channel config with prefix-aware webhook routing.

- Add tt, ttm, tts prefixes to platformPrefixes map for convID parsing
- Add TikTokType field to pancakeInstanceConfig (optional, backward compat)
- Add tiktok_type field to UI with showWhen platform=tiktok
- Add i18n labels for en/vi/zh locales
