fix: fix /start command not working - router order issue

PROBLEM:
- /start command was not responding
- Chat router was intercepting all text messages including commands
- Main router with /start handler was connected AFTER chat_router

ROOT CAUSE:
- chat_router has @router.message(F.text) handler that catches ALL text
- It was connected BEFORE main router with Command('start') handler
- chat_router returned early for /start, preventing main handler from running

SOLUTION:
1. Move main router (with /start, /help, /admin) to FIRST position
2. Keep chat_router LAST (catches only unhandled messages)
3. Remove /start and /help from chat_handlers command list (handled earlier)

ROUTER ORDER (priority):
1. router (main.py) - base commands
2. admin_router - admin panel
3. registration_router
4. admin_account_router
5. admin_chat_router
6. redraw_router
7. account_router
8. chat_router - LAST (catch-all for broadcasts)

ALSO FIXED:
- Add missing imports in admin_panel.py: Lottery, Participation, Account
- Fixes NameError crashes in cleanup functions
