This fixes 4 bugs found on a real Polres Cimahi SPRIN PDF:
1. satuan_penerbit captured the generic 'KEPOLISIAN NEGARA REPUBLIK
INDONESIA' letterhead line instead of the most-specific issuing unit
(e.g. RESOR CIMAHI / SEKTOR PADALARANG). Reworked find_satuan to
scan for each level independently and return the deepest available.
2. find_dasar_list dropped numbered items when OCR put the marker on
its own line ("1.\n Undang-Undang ..."). Refactored into
_collect_numbered_section that buffers a bare-number line and uses
the next non-empty line as the body. Also reused for the new
find_untuk_list which extracts the previously-empty 'untuk' bullets.
3. find_perihal returned None for documents that use 'Pertimbangan'
(very common in Polres-level sprint), forcing the LLM to guess.
Added a regex fallback that picks up the first line under a
'Pertimbangan' label so we keep extraction deterministic.
4. Personnel rows were emitted with only nama populated when
PP-Structure detected a table but the column mapper degraded.
Added a text-based fallback (extract_personnel_from_text) that
scans raw OCR for <rank> + <8-digit NRP> patterns. Triggered when
the PP-Structure result has fewer than 30% rank/NRP-bearing rows.
Reviewed by raising the new PERSONNEL_TEXT_FALLBACK flag.
5. Validation now flags rows with neither pangkat nor nrp as
INCOMPLETE_PERSONNEL_ROW, so the document routes to needs_review
even when individual nrp/pangkat checks pass on empty values.
6. Added 'BRIGPOL' as a variant of BRIGADIR (seen in real scans).
Tests: 229 (was 203) — 26 new tests covering the regex fixes,
text-based personnel extractor, low-quality detector, validator
behaviour, and orchestrator wiring of the fallback path.
