Replace complex Gitea API + python parsing in SSM with simple repo archive
download and extraction. Inline hardcoded paths in SSM commands instead of
shell variable expansion through single quotes to avoid quoting issues.
Replace HEAD~1 diff with git tag-based change detection to catch all changes
since last successful deploy. Split into 4 parallel jobs: detect, frontend,
API (with migrations, health check, and rollback), and deploy tagging.
- Add Gitea Actions workflow for automated frontend and API deployment
- Update all raw download URLs from GitHub to Gitea
- Remove deprecated Amplify config and GitHub-specific Terraform variables
- Clean up commented-out Amplify resources from Terraform
- Update documentation to reflect new repository and CI/CD setup
