new install not works

A fresh Docker installation is not working. I've tried different versions of release 10.
Using the following image: mattermost/mattermost-team-edition:10.10
Everything starts up, but there's no response on the port—connection hangs.

Initially, PostgreSQL showed the following error:
ERROR: relation "ir_system" does not exist

I disabled the plugin and restarted—this PostgreSQL error disappeared. The tables in PostgreSQL exist and contain data.
However, the connection on the port still hangs.

I also noticed that environment variables from .env are not being substituted into the database connection string in the config file.
I configured the connection string manually.

The only logs I see are:

{"timestamp":"2025-08-02 17:25:49.733 +03:00","level":"warn","msg":"Failed to get license from disk","caller":"platform/license.go:93","error":"We could not find the license key on disk at /mattermost/config/mattermost.mattermost-license: stat /mattermost/config/mattermost.mattermost-license: no such file or directory"}
{"timestamp":"2025-08-02 17:25:49.734 +03:00","level":"warn","msg":"License key from https://mattermost.com required to unlock enterprise features.","caller":"platform/license.go:105","error":"resource "License" not found, id: "}
{"timestamp":"2025-08-02 17:25:49.777 +03:00","level":"error","msg":"Mail server connection test failed","caller":"app/server.go:870","error":"unable to connect: unable to connect to the SMTP server: dial tcp [::1]:10025: connect: connection refused"}

Reproduce the fresh install with mattermost/mattermost-team-edition:10.10, then inspect the .env-to-database configuration behavior and the startup logs, including platform/license.go and app/server.go. Compare the plugin and PostgreSQL states while checking the port and SMTP errors; done means the documented installation responds on its port with the configuration applied and no blocking startup failure.
