cedc0c2192 feat: self-contained auth system for standalone cloud deployment (#27)
* 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

fb6c839352 feat: public landing page + split personal/business nav (#26)
* feat: public landing page with auth-conditional state

Rewrites homepage.html as a full marketing landing page serving both
unauthenticated visitors (Sign In CTA) and authenticated users (Personal
+ Business portal links). Fixes handler to pass UserID so auth-conditional
rendering activates correctly.

* feat: self-contained auth — email/password + Google OAuth, HMAC session cookies

Embeds a full authentication system into the finance API so it can be
deployed as a standalone container without any external auth dependency.

- Email/password registration and login with bcrypt hashing
- Google OAuth 2.0 (GOOGLE_CLIENT_ID / GOOGLE_CLIENT_SECRET env vars)
- HMAC-SHA256 signed session cookies (SESSION_SECRET env var, 30-day TTL)
- Sessions stored in MongoDB finance_sessions with TTL index auto-expiry
- Users stored in MongoDB finance_users with unique email index
- /auth/login, /auth/register, /auth/logout, /auth/oauth/google routes
- authMW now redirects to /auth/login?next=... instead of auth.homelab.local
- getAuth() resolves session cookie first, falls back to X-Auth-* headers
- Default categories seeded automatically on new account creation
- seed.go checks finance_users before the shared legacy users collection

7a2cb10c79 feat(finance): dark mode UI overhaul + admin seed data
UI — full dark/light theme system:
- CSS custom-property token system (--bg, --surface, --accent, --green, --red, etc.)
  with complete light-mode overrides via [data-theme="light"]
- Sticky frosted-glass nav with animated brand icon, theme toggle persisted to localStorage,
  respects prefers-color-scheme on first visit
- Cards with layered shadows, glass backdrop-filter, shimmer accent stripe on value cards
- Glowing category color dots, colored P&L badges, budget bars with glow effect
- All Chart.js instances use CSS-variable-aware grid/text colours
- Scroll-reveal animations and animated money counters on every KPI card
- 3-D donut portfolio chart recoloured to match palette; hover lifts the hovered slice
- Accounts page shows type emoji icons; delete removes row in-place
- Sharing page search dropdown themed with var() colours
- Import preview: colour-coded left border on category select driven by category colour
- Projections: second KPI card (monthly avg) + pace bars per category

Seed data (seed.go):
- SeedAdmin() runs in a goroutine at startup; idempotent (skips if transactions exist)
- Resolves admin user ID via internal users service GET /admin/users?search=<email>
  (SEED_USER_EMAIL env var, defaults to admin@homelab.local)
- Seeds 4 accounts (CGD Checking, CGD Savings, Visa Credit, Trade Republic)
- Seeds 14 categories with colours and monthly budgets
- Seeds ~65 realistic Portuguese household transactions spread across 6 months
- Seeds 7 ETF buy trades across VWCE, SXR8 (S&P 500), EUNL (MSCI World)
