Replace all ~45 direct Bot() calls across the codebase with a centralized
create_bot() factory function that automatically configures SOCKS5 proxy
session when PROXY_URL is set. This ensures proxy support applies uniformly
to all Telegram API traffic.
Key changes:
- Add app/bot_factory.py with create_bot() factory
- Replace direct Bot() instantiation in 33 files
- Fix session leaks in cloudpayments.py and auth.py (async with)
- Replace 2 direct httpx calls to api.telegram.org with
bot.create_invoice_link() (balance.py, wheel.py)
- Remove now-unused imports (Bot, DefaultBotProperties, ParseMode, httpx)
