feat(intranet): bump fc-intranet-web to v20260427-2353 + persist PageReadingOverrides

Bump intranet image to v20260427-2353 (master @ 38b0148):
- Sprint E search lane: /search Blazor page + IntranetSearchService
  + DocsCorpusIndexer + Shared.Indexing wiring
- 7 new service pages: LocalAiAgents, AiTopology, Distribution, Dns,
  Knowledge, LlmBridge, Provisioning
- PiManager drift docs

New env var: PageReadingOverrides__FilePath=/data/page-reading-overrides.json
so the persisted Lane 2α store lives on the writable PVC instead of
the default in-memory fallback (which loses state on pod restart).
Operator-edited overrides via the existing /api/v1/pages/{encoded}/overrides
controller will now survive across restarts.
