feat(web): cautare + paginare client-side pe tabelele din Mapari

Maparile pot creste la sute de randuri. Enhancer reutilizabil (data-dt) in
base.html filtreaza si pagineaza DOM-ul deja randat, fara cereri server; re-init
la full load si dupa swap-urile HTMX. Aplicat pe cele 3 tabele (De rezolvat /
operatii salvate / formate coloane).

Randurile cu <select> expun haystack explicit prin data-dt-row (cod_op + cod_rar
+ denumire): altfel optiunile selectului ar pune tot nomenclatorul in textContent
si orice cautare ar potrivi orice rand.
