feat: better install logic

[jgkawell]

This PR adds better installation logic in the operator to idempotently handle component status updates so that on retries already up-to-date components aren't repeatedly attempted to be updated.

In case you were wondering, the status field looks like this:

  status:
    daemon:
      image: ghcr.io/home-cloud-io/core-platform-daemon
      kubernetes:
        version: v1.34.3
      system:
        repo: ghcr.io/siderolabs/installer
        version: v1.11.2
      tag: latest
    gatewayApi:
      url: https://github.com/kubernetes-sigs/gateway-api/releases/download
      version: v1.4.1
    istio:
      repo: https://istio-release.storage.googleapis.com/charts
      version: 1.28.3
    mdns:
      image: ghcr.io/home-cloud-io/core-platform-mdns
      tag: latest
    server:
      image: ghcr.io/home-cloud-io/server
      tag: latest
    tunnel:
      image: ghcr.io/home-cloud-io/core-platform-tunnel
      tag: latest
    version: v0.0.1-beta

And now that the structs are all pointers, if a component is disabled, the entire object gets dropped from the status making it much cleaner.
