mattermost: 9.11.11 -> 10.5.2

- The Mattermost module ({option}`services.mattermost`) and packages (`mattermost` and `mmctl`) have been substantially updated:

  - {option}`services.mattermost.preferNixConfig` now defaults to true if you advance {option}`system.stateVersion` to 25.05. This means that if you have {option}`services.mattermost.mutableConfig` set, NixOS will override your settings to those that you define in the module. It is recommended to leave this at the default, even if you used a mutable config before, because it will ensure that your Mattermost data directories are correct. If you moved your data directories, you may want to review the module changes before upgrading.

  - Mattermost telemetry reporting is now disabled by default, though security update notifications are enabled. Look at {option}`services.mattermost.telemetry` for options to control this behavior.

  - `pkgs.mattermost` has been updated from 9.11 to 10.5 to track the latest extended support release, since 9.11 will become end-of-life during the lifetime of NixOS 25.05.

  - `pkgs.mattermostLatest` is now an option to track the latest (non-prerelease) Mattermost release. We test upgrade migrations from ESR releases (`pkgs.mattermost`) to `pkgs.mattermostLatest`.

  - The Mattermost frontend is now built from source and can be overridden.

    - Note that the Mattermost derivation containing both the webapp and server is now wrapped to allow them to be built independently, so overrides to both webapp and server look like `mattermost.overrideAttrs (prev: { webapp = prev.webapp.override { ... }; server = prev.server.override { ... }; })` now.
