fix: Ansible cleanup -- merge dual config, pin collections, align K3s version, fix bugs

Stage 4 of REFACTOR_PLAN.md.

- Merge ansible/ansible.cfg into root ansible.cfg (single source of truth);
  the dual-config setup silently broke documented commands and lost
  host_key_checking=False when run from the ansible/ directory.
- Add ansible/requirements.yml pinning community.general, ansible.posix,
  community.docker -- previously undocumented deps of the glances/watch-party
  roles that would fail a fresh bootstrap.
- Align K3s version to v1.32.4+k3s1 across roles/k3s-server, roles/k3s-agent,
  and host_vars/gpu-node.yaml defaults (was skewed: .2 vs .4). This only
  changes what a *future* provision installs -- minisforum/debian are still
  live on v1.32.2+k3s1 until separately upgraded.
- Fix kubeconfig fetch/replace path mismatch in k3s-server role: the `fetch`
  task (flat: true) writes to ~/.kube/config, but `replace` was targeting a
  /tmp/k3s-minisforum.yaml nothing creates -- would break a fresh rebuild.
- gitea-runner: only remove /run/docker.sock when it's actually a directory
  (task name implied a check that wasn't there); tighten registration-token
  systemd unit from 0644 to 0600.
- nvidia: stop unconditionally reporting `changed` (and restarting Docker)
  on every run for an idempotent runtime-configure command.
- Gate the K3s join-token debug print and WireGuard client-config/QR display
  behind opt-in vars (k3s_show_token, wireguard_show_client_configs), default
  off -- both were printing real secrets to console on every run.
- Parameterize the docker role for Debian and Ubuntu; homeassistant now
  depends on it (meta/main.yaml) instead of duplicating a Debian-only Docker
  install inline.
- FQCN cleanup across wireguard, homeassistant, and ollama roles/handlers
  (bare module names -> ansible.builtin.*/community.general.*/ansible.posix.*),
  plus a few ansible-lint name-casing/idiom fixes. Handler renames verified
  against their `notify:` call sites so notifications still fire.
- Update ansible/README.md and root README.md: add gpu-node/gpu_workstation
  (4th host, previously undocumented), docker/nvidia roles, setup-gpu-node.yaml,
  homeassistant.yaml, requirements.yml install step; correct the "Legacy"
  homeassistant label (it's the only thing serving ha.home.arpa); correct the
  Gitea ingress/backup-storage doc-drift; flag the Grafana/Loki static-PV
  binding drift discovered via live cluster check.

Verified: all playbooks pass `ansible-playbook --syntax-check`, yamllint clean.
