feat(knowledge): note types, counts, new-note button, audit fixes

- Add note_type (note/person/place/list) selector + entity metadata fields
  (relationship, email, phone / address, hours) to NoteEditorView
- Pre-select type via ?type= query param from KnowledgeView new-note dropdown
- KnowledgeView: add split "New note / ▾" button with type dropdown
- KnowledgeView: show per-type counts on sidebar filter buttons (when > 1)
- Fix: filter-btn now flex layout so count badge aligns to right edge
- Fix: list_notes count_query was missing parent_id filter (inflated totals)
- Fix: PATCH /api/notes/:id now fires upsert_note_embedding (workspace autosave)
- Fix: get_knowledge_counts endpoint for per-type counts
- Fix: get_knowledge_tags was silently discarding note_type filter (double-stmt bug)
- Fix: NoteEditorView onMounted stray brace from edit session
