Erich Blume 0e2c10176d Harden zot registry, pt 1 (#231)
## Summary
- Enable OIDC + API key authentication on zot with anonymous pull preserved
- Enforce tag immutability for version tags
- Adopt commit-SHA-based container image tagging

Details in the [[harden-zot-registry]] Mikado chain (`mise run docs-mikado harden-zot-registry`).

## Test plan
- [ ] Anonymous pull still works
- [ ] Unauthenticated push fails (401)
- [ ] CI container builds pass with new auth and tagging
- [ ] `mise run services-check` passes
