docs: sync documentation with current codebase

- Update event formatter count 23 -> 28 (add ping, workflow_job, status, deployment, check_suite)
- Document Telegram support end-to-end (routes, /gh commands, richheader, secrets)
- Fix route schema to use targets array and group fields (owners, emoji)
- Correct KV/D1 storage layout (msg:*, i18n:*, D1 links/send_logs)
- Note GITHUB_APP_ID/GITHUB_PRIVATE_KEY are unused; drop legacy DISCORD_CHANNEL_ID/PORT/CONFIG_PATH
- Remove stale Docker deployment section
- Update color table, branch filter compatibility, admin API endpoints
- AGENTS.md: add Documentation section requiring doc updates after functional changes
