Bug: VECTR_PORT and VECTR_EXTERNAL_PORT are being ignored.

Describe the bug
Settings VECTR_PORT and VECTR_EXTERNAL_PORT are being ignored.

in documenation it is said, that VECTR_PORT is for defining how tomcat will listen, but it always http and 8080
and VECTR_EXTERNAL_PORT as well is not being inserted in gateway container.

To Reproduce
Steps to reproduce the behavior:

1. Prepare env file with custom ports
2. run docker compose
3. check

Expected behavior
gateway VECTR_EXTERNAL_PORT is set as it is in env. and it will be possible to navigate to it outside containers.
VECTR_PORT - removed from docs, as it is not needed. All runs inside virtual network, so nobody cares about it

also, there is no way to redefine webui port.
