Add ability to mark case_law records as related (e.g. same appeal
through ועדת ערר → מנהלי → עליון):
- DB: case_law_relations join table (bidirectional, V11 migration)
- DB CRUD: add/remove/get_case_law_relations
- Service: get_precedent() now returns related_cases[]
- MCP: precedent_link_cases + precedent_unlink_cases tools
- REST: POST/DELETE /api/precedent-library/{id}/relations
- UI: RelatedCasesSection on detail page with search dialog and unlink

Global search rows linked to /precedents/<case_law_id> but no route
existed, so clicking a result hit a Next 404 and React threw hydration
error #418. New page reads /api/precedent-library/{id} and shows
metadata, summary/headnote/key_quote, subject tags, and the full
halachot roll-up. "ערוך פרטים" opens the existing PrecedentEditSheet
(no duplicate edit UX).
Extracted ExtractedHalachotSection + ReviewStatusPill from the edit
sheet into a shared component so both surfaces render the same block.
