fix(precedents): מראה-מקום never blank — seed at upload + inline Gemini enrichment (root cause)

Root cause: the upload form "מראה המקום" field is stored only as case_number;
citation_formatted was left empty and filled ONLY by the async metadata
extraction, which runs in the local drainer (not the container) because it was
lumped with halacha extraction. Result: the chair saw an empty מראה-מקום during
the window and re-typed it by hand.

Fix (hybrid — Option C):
- Seed: _create_external_record / create_external_case_law store the chair's typed
  citation as citation_formatted at INSERT, so the field is never blank. A
  cited_only→external promotion preserves an existing non-empty value (prior edit).
- Enrich: ingest_precedent runs metadata extraction INLINE in-container
  (gemini_session is direct REST, no local CLI) with force_citation=True, upgrading
  the seed to the canonical derived citation (parties + reporter + date) before the
  chair opens the page. Best-effort: on no key / API failure the seed remains and
  the queued metadata drain stays as the fallback. Halacha extraction is untouched
  (stays local — claude_session).
- apply_to_record / extract_and_apply gain force_citation: re-assemble even when
  citation_formatted is non-empty, writing only when assembly SUCCEEDS (seed
  preserved on abstention). The drainer keeps the default (False) so a chair's
  manual edit in /precedents/[id] is never clobbered.

Ops: GOOGLE_GEMINI_API_KEY added to the legal-ai Coolify app (runtime) — the SoT
value from Infisical nautilus:/external-apis/gemini, validated against the API.

Invariants: G2 (one citation-resolution + one metadata-extraction path, reused —
no parallel logic), INV-ID2/X1§3 (citation_formatted stays a derived field; the
seed is provisional and upgraded), INV-G10 (chair edits preserved). No schema change.
