feat(settings): Mouse tracking (Native / Wind) in View, Wind by default (#490)

[Maxaubert]

Closes #490.

What

• New Settings row View > Movement > Mouse tracking: Native (Windows' magnifier logic: DWM centres the view and draws the real pointer, Native cursor for the high resolution mode: DWM-drawn pointer with DWM centring #369) or Wind (Wind moves the view and draws its own pointer, the pre-Native cursor for the high resolution mode: DWM-drawn pointer with DWM centring #369 session from feat(cursor): txNativeCursor=0, the pre-#369 sprite cursor as an ini A/B fallback (#463) #467). Shown unless the engine is pinned to Render (the render engine always draws its own pointer).
• Default flips to Wind (owner pick). Inis that already set txNativeCursor=1 keep Native; everyone else, including fresh installs, gets Wind.
• txNativeCursor is now in the ini template; the defaults fixture, unit tests, the schema spec, docs 07/08 and CLAUDE.md follow.
• Applies at the next zoom-in (the config reload pushes it to the transform engine).

Verified

• build.bat test: all pass (fixture regenerated, one line).
• npm run test:rules 5/5, Playwright 205/205.
• Signed UIAccess deploy, Wind relaunched.
