The active hover popover stacked header + reason + presence, repeating the
same fact across lines and again against the chip. Tighten it:
- Drop the reason line for assignee / @mention: the header (name · source)
already conveys why they fire. Keep reason only for squad-leader (the link
is non-obvious) and the unknown fallback, both trimmed of the duplicated
name.
- Shorten presence (Starts right away. / Offline now — starts once online.)
and de-jargon the skip/manage hints (no more 'trigger').
- Align the popover title to the chip wording (Will start when sent).
All four locales updated; removes the two now-unused reason keys.
