fix: Resolve port conflict causing Railway healthcheck failure

Browse source 
Flask API was using PORT env variable which Railway also assigns to
the frontend static server. Both services were competing for the same
port, causing the container to fail health checks.

Changed Flask to use FLASK_PORT (default 5000) so it runs independently
from the Railway-assigned PORT used by the serve command.
