Function buildLoadConfig

pj_app/src/FileLoader.cpp:66–78

Merge the file path into the (possibly empty) saved JSON config. Saved config carries the dialog state from the previous load (delimiter, time column, etc.) so the dialog opens pre-populated. If saved_config doesn't parse, treat it as empty rather than failing the import.
