ingress_factory: replace protected bool with auth enum + audit pass across 100 stacks

Phase 3+4 of default-deny ingress plan. Replaces the `protected = bool` (default
false → unprotected) variable in `modules/kubernetes/ingress_factory` with
`auth = string` enum (default "required" → fail-closed). Touches every
ingress_factory caller so the audit decision is recorded explicitly in code.

ingress_factory (Phase 3):
- `auth = "required"`: standard Authentik forward-auth (the legacy
  `protected = true` semantic).
- `auth = "public"`: forward-auth via the new `authentik-forward-auth-public`
  middleware → dedicated public outpost → guest auto-bind. Logged-in users
  keep their real identity.
- `auth = "none"`: no Authentik middleware. For Anubis-fronted content, native
  client APIs (Git, /v2/, WebDAV), webhook receivers, the Authentik outpost
  itself.
- `effective_anti_ai` default flips ON only when `auth = "none"` (auth-gated
  ingresses don't need anti-AI noise; the auth flow already discourages bots).

Audit pass (Phase 4) across 96 ingress_factory call sites:
- 49 explicit `protected = true`     → `auth = "required"`
- 8 explicit `protected = false`     → `auth = "none"` (5) or `auth = "public"` (3)
- 64 previously-default (no protected line) → `auth = "required"` ADDED, then
  reviewed individually:
  * 9 Anubis-fronted (blog, www, kms, travel, f1, cyberchef, jsoncrack,
    homepage, wrongmove UI, privatebin) → `auth = "none"`
  * 22 native-client / programmatic surfaces (Forgejo Git+/v2/, webhook
    handler, claude-memory MCP, Nextcloud WebDAV, Matrix, Vault CLI/OIDC,
    xray VPN, ntfy, woodpecker webhooks, n8n triggers, ntfy push, dawarich
    location ingestion, immich frame kiosk, headscale CP, send anonymous
    drops, rybbit beacon, vaultwarden API, Authentik UI itself + outposts) →
    `auth = "none"`
  * Remaining ~33 → `auth = "required"` confirmed (admin tools, internal
    UIs, services without app-level auth)
- Smoke-test promotions to `auth = "public"`: fire-planner public UI,
  k8s-portal API, insta2spotify callback.

Three call sites in wrapper modules (`stacks/freedify/factory/`,
`stacks/reverse-proxy/modules/reverse_proxy/`) keep their internal `protected`
bool — they translate to `auth` internally, out of scope for this rename.

Behavior change: previously-default ingresses now fail closed (require
Authentik login) unless explicitly flipped to `auth = "none"` or
`auth = "public"`. This is the audit goal — no more accidentally-unprotected
surfaces. Sites that were intentionally public (Anubis content, native APIs,
webhooks) are now explicitly recorded as `auth = "none"`.

Drive-by: `modules/create-vm/main.tf` picked up cosmetic alignment via
`terraform fmt -recursive` during the audit. Behavior-neutral.
