Replace CAD search tab with CAD-path lookup for imported components

Browse Source 
Drop the free-text search UI; the single remaining view imports the
Distinta Base, generates the CSV, and looks up each Componente code in
the indexed DB (files_ultima_versione, prt/asm) to show its CAD file
path directly in the results grid.
