Edit document doc_type and appraiser side from the case UI

Until now changing a document's doc_type required a manual SQL update.
Adds an inline editor on the document badge so the chair can retag
without leaving the case page, and threads an appraiser_side tag
(committee / appellant / deciding) through the appraisal pipeline so
betterment-levy cases — which usually have 2-3 appraisers — render
conflicts with the deciding appraiser's view marked as governing.

Backend
- New appraiser_facts.appraiser_side column (V5.1) populated from
  documents.metadata.appraiser_side at extraction time.
- extract_appraiser_facts now returns status='sides_missing' with the
  list of untagged appraisals instead of running with empty side
  labels — chair must tag every appraisal first via the UI.
- Conflict detection orders entries committee → appellant → deciding so
  the deciding appraiser appears last; block-tet's prompt instructs the
  writer to phrase the deciding appraiser's view as the governing
  factual finding ("ואולם, השמאי המכריע קבע...").
- New PATCH /api/cases/{n}/documents/{doc_id} (Pydantic model with
  whitelist validation) and matching document_update MCP tool. Both
  merge appraiser_side into metadata JSONB instead of touching the
  schema.

UI
- New shared doc-types module exports the canonical 11 doc_type
  options plus the 3 appraiser-side options; both upload-sheet and
  the document badge now read from it instead of duplicating Hebrew
  labels.
- New DocumentTypeEditor renders a Popover off the doc-type Badge
  with two Selects. The save button stays disabled while doc_type is
  appraisal but no side has been picked, mirroring the backend
  enforcement so the user finds out before triggering extraction.
- usePatchDocument React-Query mutation invalidates the case detail
  on success so the badge updates without a manual refresh.
