Previously it only compared the top-level BOM against step/ and reported
matches, without copying anything. Now it unions the BOM codes with the
sub-components resolved in phase 4, copies every matching .stp into a new
step_finali/ folder, and reports what got created vs what's still missing.

Restructure Form1 into a sequential wizard (database -> import -> raw ->
recursive component resolution -> completeness/STEP report), fix
case-sensitivity bugs in codice/tipo_file lookups and a word-boundary gap
in the assembly scanner that missed _D100-style sub-assembly references,
and treat the distinta's general assembly as an ordinary CSV row (derived
from the DBP_<codice>_<timestamp> filename) instead of special-casing it
throughout. Also adds CadSearchGui.Tests (xUnit) covering the scanner,
filename parsing, and the case-insensitive DB lookup behavior.
