Create C2 Mikado cards for harden-zot-registry (#229)

## Summary
- Replace the old pre-Mikado plan doc (`docs/how-to/plans/harden-zot-registry.md`) with a proper C2 Mikado chain in `docs/how-to/zot/`
- Root goal: `harden-zot-registry` — enable OIDC + API key auth on zot with anonymous pull preserved
- Three leaf prereqs: `register-zot-oidc-client`, `wire-ci-registry-auth`, `enforce-tag-immutability`
- Add Zot section to `how-to.md` index, remove plan entry from plans index
- All doc checks pass (`docs-check-links`, `docs-check-index`, `docs-mikado`)

## Changes
- **New:** `docs/how-to/zot/harden-zot-registry.md` — C2 Mikado root goal
- **New:** `docs/how-to/zot/register-zot-oidc-client.md` — Register OIDC client in Authentik
- **New:** `docs/how-to/zot/wire-ci-registry-auth.md` — Wire CI push paths with registry auth
- **New:** `docs/how-to/zot/enforce-tag-immutability.md` — Prevent version tag overwrites
- **Deleted:** `docs/how-to/plans/harden-zot-registry.md` — Old plan doc (content absorbed into Mikado cards)
- **Updated:** `docs/how-to/how-to.md` — Add Zot section, remove plan entry
- **Updated:** `docs/how-to/plans/plans.md` — Remove plan entry
