fix(mobile): un-clip popups, swipe-to-reply, swipe-down-close image, no msg dance, slide-back

Browse Source 
Addresses reported iOS observations (web-side, no rebuild):
- #1: the overflow-x:hidden I added to stop sideways-scroll was clipping the profile/bell popup menus;
  now only the chat-list scroller is clipped and long content wraps instead of widening the page.
- #9: swipe a message bubble right to reply (WhatsApp/Teams style).
- #8: swipe an opened image down to dismiss the lightbox.
- #7: hide the thread for one frame on open so messages don't visibly scroll/'dance' into place.
- #4: slide the outgoing conversation off-screen on back (inline transform, reliable across WebKit).
Build marker -> 2026-07-17-batch93.
