Helm upgrade does not respect config changes

Hi,

Updating the `server.ha.config` value does not reload the configuration.

Looking at the helm templates, I think helm updates `ConfigMap` with the new values, but the server is not getting notified to reload the config.

This can be solved by recreating pods if the config changes:
[Automatically Roll Deployments](https://helm.sh/docs/howto/charts_tips_and_tricks/#automatically-roll-deployments)

Start in the Helm templates that render the server deployment and ConfigMap, using `server.ha.config` as the search term. Verify the chart's upgrade behavior and ensure that changing the configuration causes the relevant pods to be recreated, using the chart's available validation checks to confirm the result.
