feat(precedent-library): add district and chair_name to edit form

Fields existed in DB and Precedent type but were missing from:
- PrecedentUpdateRequest (backend model)
- update_case_law allowed set (db layer)
- PrecedentPatch (frontend type)
- precedent-edit-sheet form state, inputs, and patch payload
