chore: cargo fmt cleanups for emulation/macos and client_row

Pure formatting follow-ups from a code-review pass:
- input-emulation/macos.rs: move CoreFoundation imports up next to
  their core_graphics/core-foundation siblings, and let rustfmt
  collapse the IOPMAssertionDeclareUserActivity unsafe-block call
  onto a single line.
- lan-mouse-gtk/client_row.rs: rustfmt collapse of the port-title
  notify_local closure.

No behavior change.
