refactor(mac): set a window's AX messaging timeout through Window

Adds Window::set_messaging_timeout and uses it in settle.rs (the look at a
window after a drag, 3 raw AX sites) and in Window::note_arrival. Same call
on the same element; nothing changes at runtime. It is not one of the
shared Backend operations, but it bounds the frame query, so the raw AX
call leaves settle.rs with the frame read. The window manager's timeouts
list and the animator keep calling AccessibilityApi: they hold elements
(app elements, lane handles), not Windows.

Verified: macOS fake-CC type-check (tools/fast-check) PASS. Not verified:
cannot run or unit-test on Linux.
