feat(5.15+5.14): CLOSE — fix-uri code-review + embeddings functional

5.15 (propagare design + dashboard editare) si 5.14 (mapare LLM distilata)
inchise dupa /code-review high. 8 buguri reparate TDD:

- HIGH modal nu se deschidea pe randul slim (base.html: trimitere-slim)
- HIGH /repune trunchia prestatii (declaratie incompleta la RAR) -> iterare
  peste existing, codes pozitional
- HIGH embeddings incarca model ~230MB degeaba pe corpus gol -> poarta has_corpus()
- HIGH picker chips gol pe re-render eroare -> conn/account_id pe toate ramurile
- MED obs re-derivat dupa stergere explicita -> _merge_override pastreaza obs=''
- MED mapare salvata fara denumire poluă GOLD -> _record_gold_validation guard
- MED typo nome_prestatie -> nume_prestatie in select /repune
- MED bucketare timp +3h gresita iarna -> SQLite localtime + TZ=Europe/Bucharest

Embeddings WIRE-uit functional (PRD #15, decizie user): ensure_embeddings_corpus
construieste corpus din nomenclator, gated pe AUTOPASS_EMBEDDINGS_ENABLED (default
off). Marime model corectata ~50MB->~230MB (estimare PRD gresita).

Cleanup: hoist load_* din bucla bulk-fix; import re la top.
Regresie: 1256 passed, 1 deselected (live), 0 failed.

+"""Bug fix (code-review 5.15): modalul de detaliu trebuie sa se deschida la
+click/Enter pe randul SLIM.
+
+US-004 a redenumit randul listei in `class="trimitere-slim"` (ID-ul ramane
+`trimitere-row-{id}`). Handler-ele JS din base.html verificau doar
+`classList.contains('trimitere-row')` -> nu se mai potriveau pe randul slim,
+deci modalul nu se mai deschidea. Testul asserteaza ca JS-ul randat (pagina
+completa /) trateaza explicit clasa `trimitere-slim` in AMBELE handler:
+htmx:beforeRequest (click) si keydown (Enter/Space).
