Dualog Workspace

- Message forwarding: forward a message to another conversation, with a badge showing where it came from and a jump back to the original. - Full search page: search now opens a dedicated results page so you can scan every match in one place. - Faster images: chat photos and profile pictures are compressed before upload and show instant ThumbHash previews while they load. - Tidier channel list: collapse channel-list sections (remembered per device) while unread channels still stay visible. - Desktop: closing the window now minimizes to the system tray instead of quitting. - Plus polish: link insert/edit in the composer, correct file-type icons, readable dropdowns at large font sizes, better Android/iOS caching, reachable retry/discard on unsent messages, and assorted composer and scroll fixes.
