feat(precedents): minimum-effort upload — file+citation, rest auto-extracted

The missing-precedents drawer + general precedent upload both required
the user to type chair_name, district, practice_area, court, date etc.
upfront — even though those fields can be (and already are, post-upload)
extracted from the document text by the LLM. The metadata-extraction
wakeup also only fired for the /precedent-library/upload path, leaving
missing-precedents committee uploads stuck with whatever stub the user
typed.

Changes:
- Extractor learns chair_name + district, overwrites the new
  PLACEHOLDER_PENDING_EXTRACTION sentinel for internal_committee rows
  (the DB CHECK forces non-empty; we stamp the placeholder at insert).
- missing_precedent_upload no longer 400s on missing chair/district;
  it infers district from the citation when possible, falls back to
  the placeholder, and always fires pc_wake_for_precedent_extraction
  so the LLM can fill in the rest.
- Both upload sheets default to file (+ citation) only; every other
  field is tucked into a closed <details> labeled "אופציונלי — דריסה
  ידנית של שדות שיחולצו אוטומטית". Required validators on chair/
  district/practice_area dropped — the LLM fills them.
