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.

Reads the ERP-exported "Distinta Base" file (SpreadsheetML XML or real
binary .xls/.xlsx via ExcelDataReader), extracts Componente/Descrizione,
writes a CSV and previews it in a new tab alongside the existing CAD
search. Also ignore the exported Excel/CSV files dropped in the repo root.
