Refactor lane preview finalization into explicit branches so stop-created
previews never duplicate sends when edit fails.
Add Telegram dispatch regressions for:
- stop-created preview edit failure (no duplicate send)
- existing preview edit failure (fallback send preserved)
- missing message id after stop-created flush (fallback send)
Thanks @obviyus for the original preview-prime direction in #27449.
