feat(staging): runtime API-base injection via /env.js

Browse source 
Parameterize the previously hardcoded API_BASE so a staging build can point at
the staging API without forking the code:

  - env.js.template + /docker-entrypoint.d/30-fleetnow-env.sh render ${API_BASE}
    into /env.js on container start (envsubst ships with the nginx image)
  - index.html loads /env.js and uses window.FLEETNOW_API_BASE, falling back to
    the prod API (https://fleetapi.rahamafresh.com) when unset — so prod/main is
    unchanged; staging sets API_BASE=https://fleetapi.fivetitude.com
  - nginx: serve /env.js with no-store

Enables the fleetnow.fivetitude.com staging app (Coolify, staging branch).
