Largest values surface of the programme, and the first chart where the
null-safety covers two workloads.
1. values.schema.json (#68): additionalProperties: false on every
chart-owned object level, including files.barcodes, ocr (with enums
for the 3.x modes), scripts, tikaGotenberg, the oidc provider block
and the SMB CronJob.
2. Null-safety for hardening, probes and resources (#99), for the server
AND the SMB consume-mover CronJob. It reuses the defaultedDict helper
the barcodes block already introduced (#61) instead of adding a second
mechanism - one merge helper, now with more callers.
The server's pod context is consumed twice: as the pod securityContext
and by the /run-ownership init container, which chowns /run to
runAsUser:runAsGroup because s6-overlay refuses to start unless /run is
owned by the runtime uid. Both reads now go through the same helper, so
the chown cannot disagree with the context it has to match. Erasing
that block used to abort rendering with a nil-pointer error; it now
falls back to the defaults like every other chart.
The CronJob has no probes (documented exception), so only its two
contexts and resources are covered.
files.storage stays deliberately not null-safe: an erased value yields an
invalid PVC, which is the loud class #99 excludes.
Rendering is byte-identical to 11.0.0, both with the CI values (which
include the #61 regression guard) and with the production paperless-jk
bundle values.
