fix: finance upload filepath bug and add extra_hosts for keycloak auth flow

- fix NameError: filepath undefined in trigger_airflow call (use filepath_stored)
- add extra_hosts ai.sriphat.com:192.168.100.8 for container DNS resolution
  (required for KEYCLOAK_SERVER_URL=http://ai.sriphat.com/keycloak/ to work
   inside Docker — host nginx on .8:80 routes /keycloak/ to Keycloak container)
