Replace go-telegram-bot-api/v5 (2021, no forum topics) with
go-telegram/bot v1.20.0 (Bot API 9.5) via TGSender adapter pattern.
- New TGSender interface + tgBotSender implementation isolating library
- Native message_thread_id support: saved at /bridge, used in MAX→TG
sends, echoed in all command responses, looked up in queue retries
- All 16 files migrated, zero old library references remain
- Proper error wrapping: MigrateError, Forbidden, BadRequest, NotFound,
TooManyRequests → TGError with codes
- ForwardFromChat → ForwardOriginChat (Bot API MessageOrigin pattern)
- Repository: GetTgThreadID/SetTgThreadID (migration 000012 already applied)
- Tests for convertMsg, convertCallback, wrapErr, toInputFile,
toLibInputMedia, tgEntitiesToMarkdown, maxMarkupsToHTML

Per-crosspost configurable find/replace rules applied during forwarding.
Supports string and regex replacements, scoped to full text or links only.
Each direction (TG→MAX, MAX→TG) has its own set of rules.
UI: inline buttons for add/delete/toggle target type in both TG and MAX bots.
Closes#14
