fix(frontend): resolve production API URL fallback to localhost

Problem:
The unified Docker image builds the frontend at build time without
VITE_API_URL. Vite inlined import.meta.env.VITE_API_URL as undefined,
so every API call fell back to the hardcoded 'http://localhost:8080'.
This broke Casa deployments where the frontend loaded from the public
 domain but tried to reach the backend at localhost.

Solution:
1. Centralize API URL resolution in lib/api-url.ts via getApiOrigin().
   It checks runtime window.ENV first (injected by docker-entrypoint.sh
   at container startup), then build-time import.meta.env, then dev
   fallback. In production unified deployments it returns '' so API
   calls use same-origin relative URLs (/api/v1/...) that nginx proxies
   to the backend.
2. Replace all 50+ inline import.meta.env.VITE_API_URL || 'localhost'
   usages across 14 source files with getApiOrigin() / getApiV1BaseUrl().
3. Add build args and runtime sed substitution to Dockerfile and
   docker-entrypoint.sh so the same image works for any deployment.
4. Pass VITE_API_URL through docker-compose.yml and CI/CD build-args.

Verified:
- Production bundle contains 0 occurrences of localhost:8080.
- Container health check and /api/v1/auth/check-users both return 200.
- Runtime injection correctly sets VITE_API_URL='' for same-origin
  and VITE_API_URL='https://domain' for external backend.

+### One-Command Deployment (Docker Run)
+
+PostgreSQL is bundled inside the image. Zero external dependencies.

-```bash
-git clone https://github.com/dvorinka/trackeep.git
-cd trackeep
-cp .env.example .env
-# Edit .env file with your configuration
-docker compose up -d

-### Service Architecture
+**Why this is CasaOS-ready:**
+- **Single service** — PostgreSQL runs inside the same container
+- **No `BACKEND_PORT`** — internal backend runs on 8081, only port 8080 is exposed
+- **Named volumes** — CasaOS handles them automatically
+- **Optional env vars** — if `DB_PASSWORD` or `JWT_SECRET` are empty, the container auto-generates them
+- **Icon header** — CasaOS reads the `icon:` field for the app tile

-- **Health**: HTTP health check endpoint
-- **Auto-configuration**: Frontend automatically connects to backend via nginx proxy
