feat(web): UI compact Trimiteri + bara bulk contextuala + fix buton "+" editor (PRD 5.22)

Trimiteri desktop = tabel grid cu header, un rand per trimitere: status =
bulina cu tooltip, mediu = litera T/P, multi-cod = primul cod + badge +N,
sub-linie de eroare cu textul brut RAR doar pe error/needs_data. Mobil:
2 linii prin grid-areas, fara header. Actiunile bulk apar doar la selectie
(bara contextuala cu contor + texte explicite). Mapari: exemplu concret in
loc de descriere la Reguli automate.

Fix buton "+" chips (nu facea nimic, fara eroare): hx-disabled-elt="find
button" mostenit de la form-ul parinte crapa htmx inainte de request ->
hx-disabled-elt="this" explicit pe butoanele chips; separat, no-op-urile
silentioase din post_form_chips au acum mesaje (cod invalid/duplicat) si
confirmare cu chip evidentiat la succes.

Suita: 1622 passed. Verify E2E in browser (desktop 1280 + mobil 390).
