Type node creation and filter local memory by effective type

- nap_create_node accepts `type`; when omitted (also in nap_bulk and
  agent-node creates) the type is inferred from the folder and sent
  explicitly, so older APIs also store typed plans and decisions.
  Explicit spelling variants are canonicalized; custom types pass as is.
- Local browse, full-text and encrypted-shard searches filter on the
  effective type (canonical spelling, or the folder's type for generic
  notes; `type=note` excludes notes whose folder implies a type); server
  rows are post-filtered the same way. Rows expose `effective_type` when
  it differs from the stored type; discover offers an effective_type
  facet.
- Active-only filters also exclude deployed, released,
  released_verified_production and folded.
