refactor: Remove deprecated INTERNAL_API_PORT (ultrathin monolith cleanup)

Architecture cleanup after migration to ultrathin monolith:

- Remove INTERNAL_API_PORT from .env files (was port 8002)
- Clean up bot_main.py: remove uvicorn, Thread, run_internal_api()
- Update validate.md to check /api/telegram/health instead of port 8002
- Add deprecation notices to old Windows deployment docs
- Update docs/telegram/README.md with architecture note

The Telegram internal API is now served at /api/telegram/internal/*
on the main backend port (8000/8001) instead of separate port 8002.

Also includes: menu updates, ServerLogsView improvements, script fixes
