1. Message-info popup: ONE scroll region for the whole list with sticky
Seen / Not-seen headers (was a separate scrollbar per section), realigned.
2. Group message notifications now title = GROUP name, body = "Sender: text".
3. Unread taskbar badge: solid red rounded-square (Teams-style) + white outline
instead of the gradient disc.
4. Pasting Excel/Sheets cells no longer uploads a screenshot — when the clipboard
carries real text, the text is pasted; image-only clipboards still upload.
5. Spell check in the message box (red squiggles) with a right-click menu of
corrections + add-to-dictionary; spellcheck enabled on the textarea.
