Add toggles to enable/disable notification channels

- Add telegram_enabled, discord_enabled, pushover_enabled columns to database
- Update notification service to check enabled status before sending
- Add toggle switches in Settings UI for each configured channel
- Update ProductDetail to only show badges for enabled channels
- Channels default to enabled so existing users keep notifications
