fix(electron): add screen and display-capture to Electron permission allowlists

setPermissionCheckHandler and setPermissionRequestHandler only allowed
["media", "audioCapture", "microphone", "videoCapture", "camera"], causing
any renderer-side getUserMedia/desktopCapturer request using a screen source
to be silently denied by Electron before macOS TCC is ever consulted.

Fix: add "screen" and "display-capture" to both handler allowlists.
