Task 4 of #582. Add 'process' to the knowledge route _VALID_TYPES and to the
get_knowledge_counts facet + total. query_knowledge/_apply_type_filter already
handle arbitrary note_type, so listing by type=process works unchanged.

Backend:
- GET /api/knowledge/ids: returns up to 100 note IDs cheaply (no body
parsing), supports same filters as /api/knowledge, includes has_more
- GET /api/knowledge/batch?ids=...: fetches full items for given IDs in
order; used by frontend to load content in controlled batches
Frontend (KnowledgeView):
- Fetch 100 IDs upfront, load first 50 as content on mount
- IntersectionObserver sentinel (root: null) triggers 24-item content
batches as user scrolls
- Proactive ID refill when queue drops below 48 unloaded IDs
- fetchGen counter invalidates stale in-flight responses on filter reset
- IDs claimed before async fetch to prevent double-loading
- sentinelVisible ref drives post-load re-check when content doesn't
push sentinel off screen
