Rebrand Pinscope to Periscope across product and codebase.

Rename the core package to periscopex, update UI/docs/Docker/deploy defaults to periscope.michelebigi.it, and keep legacy version/storage key aliases so existing projects keep working.

+"""BOM vs schematic property matching.
+
+Compares per-reference MPN/value from the schematic property table against
+the uploaded BOM. Silent when the schematic map is empty (PADS/EDIF) so
+we never invent orphans from a format that has no schematic properties.
