Gonçalo Rodrigues 05dd725579 feat(infra): Gitea self-hosted CI/CD + MongoDB PVC + registry pipeline (#28)
* fix(k8s): expose / without auth so homepage is publicly reachable

Adds a second Ingress (api-public) for the exact path / with no
forward-auth middleware. Traefik prefers the Exact match for the root,
while the Prefix ingress (with auth) still protects all other routes.

* fix: homepage renders correctly at / for unauthenticated visitors

Two fixes:
1. Added parseStandalone() helper — parseTmpl() roots on "" but ParseFS()
   stores standalone (no {{define}}) files under their base filename, so
   Execute() ran the empty root and returned Content-Length: 0.
2. Added router.priority: 100 annotation to api-public ingress so Traefik
   picks the Exact / rule over the Prefix / rule (Traefik ranks by rule
   string length by default, which made PathPrefix beat Path).

* fix(k8s): remove forward-auth middleware from finance ingress

The app now handles its own auth at /auth/login — Traefik no longer
needs to forward-auth requests, which was causing redirects to
auth.homelab.local instead of finance.homelab.local.

* feat(auth): harden authentication for cloud deployment

1. Secure cookie flag — set when BASE_URL starts with https://
2. SameSite=Strict on session cookie (was Lax)
3. Rate limiter — per-IP, 10 failures → 15-min lockout, auto-cleanup goroutine
4. Session rotation on login — old session deleted before issuing new one
   (prevents session fixation attacks)
5. bcrypt cost 12 (was DefaultCost/10, OWASP minimum for cloud)
6. Security headers middleware on all responses:
   X-Content-Type-Options, X-Frame-Options, Referrer-Policy,
   Permissions-Policy, Content-Security-Policy, HSTS (when HTTPS)
7. Structured audit logging — login success/failure/lockout with IP + email
8. Google OAuth state cookie gets Secure flag too

* feat(infra): Gitea self-hosted CI/CD + MongoDB PVC + registry pipeline

- Add Gitea Helm deployment (git hosting, container registry, Gitea Actions)
- Add act runner with DinD sidecar for Docker builds in-cluster
- Add RBAC so act runner can kubectl-deploy to finance namespace
- Fix MongoDB StatefulSet: add volumeClaimTemplates (data was lost on restart)
- Configure k3d containerd to mirror git.homelab.local → Gitea NodePort 30002
- Add .gitea/workflows/finance-api.yml: test → build/push → rolling deploy
- Update finance-api deployment: Gitea registry image, imagePullPolicy Always
- Extract finance-api secrets (SESSION_SECRET, Google OAuth) into Terraform
- Add variables.tf for Gitea admin password and runner token

All changes testable on local k3d before the VPS exists.
