Subject: [PATCH] fix(frontend): use relative baseURL in production, avoid
 hardcoded localhost

Previously baseURL defaulted to 'http://localhost:5001' in all environments,
causing issues when deployed on servers or Docker with port mapping.

Changes:
- Use relative path (empty string) in production for same-origin deployment
- Keep localhost:5001 default for development environment
- Still respects VITE_API_BASE_URL env var if set

Fixes #93, related to #59, #57
