feat(proxy): enhance Traefik version notifications to show patch and minor upgrades

- Store both patch update and newer minor version information simultaneously
- Display patch update availability alongside minor version upgrades in notifications
- Add newer_branch_target and newer_branch_latest fields to traefik_outdated_info
- Update all notification channels (Discord, Telegram, Slack, Pushover, Email, Webhook)
- Show minor version in format (e.g., v3.6) for upgrade targets instead of patch version
- Enhance UI callouts with clearer messaging about available upgrades
- Remove verbose logging in favor of cleaner code structure
- Handle edge case where SSH command returns empty response
