Remove #if WINDOWS blocks and fix PortAudio CI bundling

- Remove all #if WINDOWS conditional compilation blocks from App.axaml.cs:
  ConfigurePlatformDllPaths/SetDllDirectory call, Discord RPC teardown,
  and the SetDllDirectory P/Invoke declaration
- Drop unused System.Runtime.InteropServices using directive
- Place bundled portaudio.dll alongside the executable in CI output
  rather than in a runtimes subdirectory
