Feature Request: Environment variable for lizmapPluginAPIURL

Problem

Currently, the lizmapPluginAPIURL setting in Lizmap Web Client is hardcoded to use http://map:8080/lizmap/ as shown in the official documentation. This creates issues in multi-tenant Docker deployments where multiple Lizmap instances run on the same Docker network.

When multiple stacks share the same network (e.g., traefik_default), the network alias map creates conflicts because Docker randomly routes requests to one of the containers using that alias.

Current Workaround

The only solution is to create a separate internal network for each stack with dedicated aliases:

• Stack 1: geoportal_internal_stack1 network with alias map
• Stack 2: geoportal_internal_stack2 network with alias map
• etc.

This works but increases network complexity.

Proposed Solution

Add an environment variable (e.g., LIZMAP_PLUGINAPIURL) to allow customization of the plugin API URL, similar to how LIZMAP_WMSSERVERURL already works.

Example:

environment:
  LIZMAP_WMSSERVERURL: http://geoportal-stack1:8080/ows/
  LIZMAP_PLUGINAPIURL: http://geoportal-stack1:8080/lizmap/
