Add commit URL to Slack notifications with link and backtick formatting

Browse Source 
- Add commit_url column to webhook_events and deployments tables
- Extract commit URL from webhook payload (from commit object or repo URL)
- Format Slack messages with backticks for branch and commit SHA
- Link commit SHA to the actual commit URL on the git server
- Keep plain text format for ntfy notifications
