Migrate from GitHub to Gitea with CI/CD

- 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
