feat(apple): transfer controls, progress fixes, and project config

- Sender progress: aggregate only in-flight receivers so the bar clears on
  completion and is order-independent ("Sending to N")
- Add Stop sharing and per-receiver Refuse (pending requests) on the sender
- Fix macOS: raise approval modal above the Share sheet; drive foreground
  state off NSApplication so background notifications fire
- Persist app identity (display name, category) and signing team via
  Info.plist / project.yml / gitignored Local.xcconfig
