Replace Rust prefix setup with C++ step-by-step dialog

Move Wine prefix creation from NaK Rust FFI to native C++ with a new
modal dialog showing per-step progress, retry support, and proper
failure cleanup.

- PrefixSetupRunner: runs each step (proton init, drive cleanup, 11
  individual winetricks verbs, .NET installers, game detection, wine
  registry, win11 mode, post-setup) as discrete retryable operations
- PrefixSetupDialog: step list with status icons, filtered log output,
  cancel/retry-failed/delete-prefix buttons
- Downloads use QNetworkAccessManager (no host curl dependency)
- Zip extraction uses downloaded 7zz binary (no host unzip dependency)
- Winetricks runs on host (not in pressure-vessel) so cabextract is
  always findable via PATH
- Wine/winetricks debug spam filtered from log output
- Skip Python basic_games proxy since native equivalent exists
