feat(ux): import compact + preview format Trimiteri + navigatie + scoatere auto_send (5.11)

8 stories TDD (echipa Sonnet, lead orchestreaza). US-001 scoate hold-ul auto_send din mapare
(has_no_auto_send->False, simbol pastrat; cod rezolvat->queued). US-002 scoate bifa auto_send
din UI. US-003 preview pas 3 in format .tabel-trimiteri (STARI_PREVIEW + nota_umana_preview,
fara repr Python; view-model prez). US-004 filtre layout/stil ca referinta + buton Custom.
US-005 navigatie Trimiteri/Mapari sub contoare pe toate paginile. US-006 import <details> nativ
colapsabil. US-007 post-commit reveal (OOB _coada/_status + HX-Trigger). US-008 auto-refresh
dupa actiuni (nudge eliminat).

VERIFY context curat PASS (8/8). /code-review high: 3 buguri reparate (tab nav la self-refresh,
pill Custom valori stale, nota_umana_preview precedenta needs_mapping). 934 passed, 1 skipped.
Backend trimitere + schema NEATINSE.
