fix: convert all workflows to standard htpasswd pattern (no artifacts)

- Removed artifact upload/download steps from all workflows
- Merged build+test into single 'test' job, eliminating artifact dependency
- Removed ChristopherHX/gitea-upload-artifact and download-artifact actions
- Builds image directly with docker build and runs tests in same job
- Push job rebuilds independently with docker/build-push-action
- pr.yaml: lint → test only (no push/version bump)
- tag.yaml: lint → test → push with semver tags
- cron.yaml: keeps original '0 0 * * *' schedule
- All pinned SHAs preserved
