admin 1d08156d81 version tracking: tune annotations + add customManagers for linuxserver servarr
Several images were showing as outdated in version-checker / unhandled by
Renovate. Each had a distinct cause; this PR fixes the auto-tractable ones.

1) admin-system/renovate.yaml: bump `app.kubernetes.io/version` labels
   `43.197.0 -> 43.209.3` (3 occurrences) to match the live image.
   Renovate's own self-update PR bumped the image tag but left the
   labels stale; the version-checker widget appears to read the label.
   Long-term, this label will drift again on each self-update -- worth
   a customManager later if it becomes a recurring annoyance.

2) admin-system/renovate.yaml: add a customManager + packageRule pair
   for linuxserver servarr apps. Tag pattern is `version-X.Y.Z.B`
   (4 segments + `version-` prefix) which the kubernetes manager's
   default docker versioning rejects at the pre-check, same failure
   class as termix. Regex versioning parses the prefixed 4-segment
   form; the same customManager handles prowlarr/radarr/sonarr (depName
   captured from the regex). kubernetes-manager extraction for these
   three depnames is disabled via packageRule so the dashboard isn't
   cluttered with the failing fallback.

3) nextcloud-system/nextcloud.yaml: add
   `match-regex.version-checker.io/nextcloud: '^\d+\.\d+\.\d+-apache$'`
   so version-checker doesn't treat the bare `33.0.5` server tag as a
   newer version of our `33.0.5-apache` image. The widget was showing
   `33.0.5-apache -> 33.0.5` -- false positive; image is already current.

4) helm/plex/values.yaml: tighten the version-checker regex from
   `^\d+\.\d+\.\d+\.\d+-.*$` to `^\d+\.\d+\.\d+\.\d+-[a-f0-9]+$` so
   per-arch tags (`-armhf`, `-arm64`, ...) are excluded. The widget
   was showing an `-armhf` tag as "newer" than our x86_64 install.

# Renovate Bot - Self-hosted dependency updater
# ============================================
# https://docs.renovatebot.com
# Image: renovate/renovate (plain tag = minimal image, "formerly slim";
# -slim suffix was retired after v37.440.x, so we pin the plain tag)
#
# PILOT SCOPE (intentionally narrow):
# Runs weekly (Sat 02:00 Europe/Budapest) as a CronJob and opens
# dependency-update PRs against admin/homelab-manifests on Gitea.
# Only the `kubernetes` and `helm-values` managers are enabled, and a
# default-deny packageRule limits updates to exactly four pilot images:
# - ghcr.io/thomiceli/opengist
# - louislam/uptime-kuma
# - f0rc3/gokapi
# - docker.io/calcom/cal.com
# minor/patch -> PR with Gitea native auto-merge; major -> waits for
# manual approval via a checkbox on the Dependency Dashboard issue.
#
# Stateless & ephemeral: no Service, Ingress, or PVC. Writable /tmp is an
# emptyDir (root FS is read-only); Renovate uses it for git clones + cache.
#
# Secrets (created manually, NOT in git) come from Secret `renovate-secrets`:
# - RENOVATE_TOKEN (Gitea PAT)
# - RENOVATE_GITHUB_COM_TOKEN (GitHub PAT, for release notes)
# ============================================
