Delete dead Flask-based PAL24 webhook server (app/external/pal24_webhook.py).
PAL24 webhooks already handled by unified FastAPI server on port 8080.
- Remove flask dependency from pyproject.toml and requirements.txt
- Remove PAL24_WEBHOOK_PORT config (unused, FastAPI uses shared port)
- Remove pal24_webhook module reference from log filter
- Update docs: webhook example rewritten from Flask to FastAPI
- Uninstall flask, werkzeug, blinker, itsdangerous
Remove AUTO_ACTIVATE_AFTER_TOPUP and SHOW_ACTIVATION_PROMPT_AFTER_TOPUP
features from all payment providers, config, system settings, and tests.
Cart auto-purchase (AUTO_PURCHASE_AFTER_TOPUP) is preserved.

- fix TelegramForbiddenError not caught in photo_message.py
- fix "query is too old" spam in required_sub_channel_check
- add missing trial locale keys (TRIAL_PAYMENT_DESCRIPTION, TRIAL_REFUND_DESCRIPTION, TRIAL_ACTIVATION_ERROR)
- Add pyproject.toml with uv and ruff configuration
- Pin Python version to 3.13 via .python-version
- Add Makefile commands: lint, format, fix
- Apply ruff formatting to entire codebase
