Subject: [PATCH] fix(home-assistant-mcp): use RollingUpdate and allow
 image.tag override

Recreate strategy caused full downtime when a chart appVersion bump
referenced an unpublished image tag. Switch to RollingUpdate with
maxUnavailable=0 so the old pod stays up until the new one is Running,
and add an image.tag override so consumers can pin to a working tag
when appVersion races ahead of the published image.
