ocs_doc_api: Phase 5 (media & misc, read-mostly)

- entity_kind_name names the media/misc families (RasterImage, Table, Leader,
  MultiLeader, MLine, Mesh, Helix, Region, Body, Surface, Face3D, Dimension,
  Hatch) so GetEntity reports a real kind instead of 'Other'.
- RasterImage coarse bounds (insertion + u*width + v*height).
- Generic delete already works on these families; no typed create in v1
  (read-only EntityView per plan).
- spec RasterImage/Table read-mostly families; IMPLEMENTATION.md updated.
- Test phase5_media_entities_read_kind_and_bounds -> 601 host lib green.
