fix: qbittorrent/jdownloader crash-loop from today's rollout

Both Deployments' rolling update briefly ran an old+new pod pair on the same
node (node-role: storage), sharing the same config storage (qbittorrent's PVC,
jdownloader's hostPath) -- both apps are effectively singletons that lock
their config directory, so the new instance conflicted with the still-running
old one:

- qbittorrent: hit a known qbittorrent:5.2.0 image bug (linuxserver/
  docker-qbittorrent#432) where a stale WebUI lockfile prevents the server
  from ever binding its port while a second instance is present -- surfaced
  as the new pod's readiness probe getting "connection refused" indefinitely.
  On top of that, my livenessProbe (30s/30s) was killing the container
  (exitCode 137) before qbittorrent had any chance to come up at all. Dropped
  the livenessProbe (readiness alone can never kill a container, only mark it
  not-ready) and loosened the readinessProbe timing.
- jdownloader: the new pod's app process detected the old instance's lock in
  the shared /data/jdownloader hostPath and exited cleanly (exitCode 0) rather
  than run a duplicate copy -- nothing to do with probe timing.

Both Deployments now use `strategy: Recreate` instead of the RollingUpdate
default, so any future rollout fully stops the old pod before starting the
new one -- this is the actual fix (matches the pattern immich.yaml already
used). Applying this will briefly restart both currently-running pods to
verify it.
