Pull request overview

This PR implements importing network profiles from a CSV file (closing #3492). It cleanly mirrors the existing Active Directory import architecture: a new import source is added to the method picker, a source-specific dialog parses the file into ProfileImportCandidates, and those candidates flow into the shared ImportProfilesResultViewModel for review, duplicate detection, and final import. The implementation reuses established patterns (child-window sizing, drag-and-drop, validators, RelayCommand, settings persistence, and localized resources), so it integrates consistently with the existing profile-import subsystem.

Changes:

• Adds CsvProfileImportParser (delimiter auto-detection, optional header, quoted-field handling, SHA-256 based duplicate key) plus the ProfileImportSource.Csv enum value.
• Adds the ImportCsvFileViewModel/ImportCsvFileChildWindow dialog and wires it into ProfileDialogManager and ImportProfilesViewModel, with a new Profiles_ImportCsvLastFilePath setting and CsvFileExtensionFilter.
• Adds localized strings/designer entries plus documentation and changelog updates.
