fix(import): route a double-clicked .aeroftp export to the import flow

Only .aerovault and .aeroftp-keystore were forwarded from the
single-instance and macOS first-launch argv handlers. A plain .aeroftp
server-profiles export was a registered file association, so it opened
the app, but no event was emitted and importAeroFtpProfileFile() was
never called: the file dead-ended on a bare window (issue #214 pt.4a,
plain .aeroftp).

Emit servers-open-file from both handlers and add a frontend listener
that drives the existing password-prompt import flow. ends_with(".aeroftp")
does not match ".aeroftp-keystore", and the listener additionally guards
!endsWith('.aeroftp-keystore'), so keystore files never reach the
profiles importer.
