fix: complete remaining remediation (#5, #8, #9)

#5 Gateway Trust Model:
- Token validation now uses protected endpoints, not health checks
- Unknown services rejected (no fallback to unprotected endpoint)
- Trust model documented in docs/trust-model.md

#8 CI Enforcement:
- Added .gitea/workflows/security.yml with:
  - Dependency audit (npm audit --audit-level=high for budget)
  - Secret scanning (checks for tracked .env/.db, hardcoded secrets)
  - Dockerfile lint (non-root USER, HEALTHCHECK presence)

#9 Performance Hardening:
- Budget /summary: 1-minute in-memory cache (avoids repeated account fan-out)
- Gateway /api/dashboard: 30-second per-user cache (50x faster on repeat)
- Inventory health endpoint added before auth middleware

Closes #5, #8, #9

+# Gateway Trust Model
+
+## Architecture
+
+All frontend requests go through: Browser → Pangolin → frontend-v2 (SvelteKit hooks) → gateway → backend services.
+
+## Authentication Layers
+
+### Gateway (platform auth)
+- Users authenticate via `/api/auth/login` with username/password (bcrypt)
+- Session stored as `platform_session` cookie (HttpOnly, Secure, SameSite=Lax)
+- All `(app)` routes require valid session (checked in `+layout.server.ts`)
+
+### Service-level auth
+Each backend service has its own auth mechanism. The gateway injects credentials when proxying:
+
+| Service | Auth Type | Injected By Gateway | Validated Against |
+|---------|-----------|--------------------|--------------------|
+| Trips | Bearer token | `Authorization: Bearer {token}` | `/api/trips` (protected endpoint) |
+| Fitness | Bearer token | `Authorization: Bearer {token}` | `/api/user` (protected endpoint) |
+| Reader | API key | `X-Auth-Token: {key}` | `/v1/feeds/counters` |
+| Inventory | API key | `X-API-Key: {key}` | `/summary` |
+| Budget | API key | `X-API-Key: {key}` | `/summary` |
+| Books (Shelfmark) | None (proxied) | — | Gateway auth only |
+| Music (Spotizerr) | None (proxied) | — | Gateway auth only |
+
+### Frontend hooks auth (SvelteKit)
+- Immich proxy: validates `platform_session` cookie before proxying
+- Karakeep proxy: validates `platform_session` cookie before proxying
+- Legacy trips Immich: validates `platform_session` cookie before proxying
+
+## Service Connections
+- Users connect services via Settings page
+- Token validation uses a **protected endpoint**, not health checks
+- Unknown services cannot be connected (rejected with 400)
+- Tokens stored in `service_connections` table, per-user
+
+## Internal Network
+- All services communicate on Docker internal network
+- No service port is exposed to the host (except frontend-v2 via Pangolin)
+- Gateway is the single entry point for all API traffic
+
+## TLS
+- External HTTPS: default TLS verification (certificate + hostname)
+- Internal services: `_internal_ssl_ctx` with verification disabled (Docker services don't have valid certs)
+- Image proxy: default TLS verification + domain allowlist
+
+## Secrets
+- All secrets loaded from environment variables
+- No hardcoded credentials in code
+- `.env` files excluded from git
+- Admin credentials required via `ADMIN_USERNAME`/`ADMIN_PASSWORD` env vars
