feat(web): dashboard compact — import pe Acasa, status cu bife, Trimiteri lizibile, Mapari complete (3.5)

Acasa = ecran de import (tab Import scos, ?tab=import->Acasa). Bara status
compacta pe 2 randuri cu bife accesibile (glife + text) + data formatata.
'Coada'->'Trimiteri': coloane RO, stare umana, detaliu la click in panou
dedicat. Mapari pe 3 sectiuni (de rezolvat / op salvate / formate coloane),
Cont doar cheie+creds. Filtrare Trimiteri, corectie inline needs_data cu
re-enqueue + detectie coliziune idempotency, badge contoare pe tab-uri.
Helper pur partajat payload_view.py (web + GET /v1/prezentari).
Backend trimitere (worker/idempotenta/mapping/schema) neatins. 483 teste.
