feat(paperless-ngx)!: quote every operator scalar, pin the consume mover, drop oidcSecretRef

Three issues on one chart, bundled because they share values.yaml,
values.schema.json and the version line, and because the first half of #11
lives in the same template as #101.

Gitea #11, first half: the consume CronJob's schedule was rendered bare, so a
schedule in the commonest cron notation there is - a star, a slash, an interval
- aborted the render with a YAML parse error pointing at the template while the
operator's value appeared nowhere in the message. Quoting it in the values file
does not help; Helm passes the content through. Reproduced before the fix, at
the line the issue names, and fixed with | quote.

Gitea #11, second half: secrets.oidcSecretRef is removed, values and schema
both. No template ever read it, so no OnePasswordItem was created and nothing
reached the pod - the quiet kind of defect that looks like successful
configuration. It is not reimplemented, and the reason is in paperless: the
whole OIDC configuration travels in one json environment variable with no _FILE
variant, so a secretKeyRef cannot substitute a fragment into it. The
operational question is answered by #83 - Keycloak marks a client public per
client, so nothing forces a confidential one here.

In the same breath, oidc.provider.tokenAuthMethod is restricted to "none". Its
comment named client_secret_basic as the example, which asks the provider for
an authentication this chart cannot perform: it configures no client secret and
cannot. The two values read together looked like a working secret setup, and the
symptom was a login dying at the callback with invalid_client. No live release
sets it (measured against all three instances).

Gitea #112 asked for an extraEnv and the chart already had the standard
additive env block - the issue was measured against a deployed 12.2.0 and read
only the top-level keys. What was actually broken is the block itself: it
rendered its operand bare, so a "*"-leading value aborted the render and "true"
or "0755" arrived as a bool or an integer, which the API server rejects after a
green render. It is brought to the repository's documented quoted form
(template-chart carries the rule), which is what makes an arbitrary PAPERLESS_*
variable settable in practice. PAPERLESS_LOGGING_DIR is documented as the
worked example, with the cross-reference it needs: the root cause is the
NFS-exported RWX data volume in jk-cluster-config #360 and this does not fix it
- it only moves the log off that volume. The two Ingress upload-size
annotations had the same bare render and are quoted too.

Gitea #101: the consume mover now runs on the node of the StatefulSet pod, via
a required podAffinity on its label. It mounts the RWX consume volume, and
Longhorn's CSI driver refuses that mount unless it finds a workload pod in
Pending, so a mover on another node left the StatefulSet node's kubelet
retrying every two minutes - 291 events in 10 hours in both releases with SMB
on, none in the release without the CronJob. A static nodeSelector would be
wrong because the StatefulSet pod is not pinned either, and preferred would
reproduce the bug more rarely and harder to find.

The cost of a required term is handled rather than left open:
concurrencyPolicy: Forbid, a startingDeadlineSeconds that also keeps the
controller away from its 100-missed-schedules stop, and an activeDeadlineSeconds
that fails a job which cannot be placed instead of leaving one Pending pod per
schedule. scaleDown already suspends the CronJob; what remains is
paperless.replicas: 0 with SMB on, which now reports a bounded, visible failure.
successfulJobsHistoryLimit is deliberately untouched: Longhorn's check asks for
the existence of a Pending pod, not the absence of Succeeded ones, so those
three pods are the error message's evidence and not its cause.

Side defect fixed on the way: every read of smbConnection.cron dereferenced the
block directly, so an override that had erased it aborted with a nil-pointer
error naming an internal template path instead of falling back to the defaults
this chart promises everywhere else. Measured on origin/main; all reads now go
through a merged-defaults helper that preserves an explicit false.

Major: a value is removed and fails the strict schema afterwards, and runtime
placement changes.
