fix(pwa): the installed app can rotate, and "New Message" opens a new DM (#292)

manifest.json locked the installed app to portrait (no landscape video,
screenshare or call view on Android / tablets) and its "New Message"
shortcut pointed at /, the home page. Drop the orientation lock and
point the shortcut at ./direct/create/ (Create Chat).

Fixes #292
