fix(frontend): resolve production API URL fallback to localhost
CI/CD Pipeline / Test (push) Successful in 20m59s
CI/CD Pipeline / Security Scan (push) Successful in 10m38s
CI/CD Pipeline / Build and Push Images (push) Failing after 13s

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.
