feature: add Input Symbol Map field to GUI advanced settings (#26)

Completes the #26 GUI follow-up. The project's Advanced Settings dialog now has an
'Input Symbol Map' field (text box with file drag-drop + a browse button) bound to
ProjectVM.InputSymbolMap, so users can select a previous symbols.map from the GUI
for consistent re-obfuscation. Round-trips through the existing project save/load.
