feat(slice4): schema-driven metadata edit panel in RFCView (§22.4a PUC-1 §5.2)

MetadataFieldsPanel renders one control per declared field (enum→select, tags→chips, text→input), read-only without contribute access, saving changed values via saveEntryMeta (direct sidecar commit). Wired into the canonical main view, gated on the collection declaring fields (INV-5). saveEntryMeta API client added. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
