fix(#77 frontend): separate מספר-תיק field on committee upload + editable case_number in edit sheet

Pairs with the backend PR. Stops the citation (מראה-מקום) from being stored
as the identifier, and lets a wrong identifier be corrected after the fact.

- upload sheet: new required 'מספר תיק (מזהה ייחודי)' field for committee
  decisions → sent as case_number; the citation field is now sent as the
  separate citation (→ citation_formatted) instead of as case_number.
- edit sheet: the case_number block is now an editable input (was read-only).
  Halachot/chunks key off case_law_id (UUID), so renaming case_number is safe.
- precedent-library.ts: InternalDecisionUploadInput += citation; PrecedentPatch
  += case_number.
- types.ts: regenerated (api:types) — PrecedentUpdateRequest now carries
  case_number.
