feat(ui): marquee-scroll selected long names/labels instead of static ellipsis

Browse Source 
Selecting a row whose ellipsized text overflows now animates a "swing"
marquee: holds at the start, scrolls to reveal the full tail, holds
there, then scrolls back and repeats. Unselected/non-overflowing text
is unchanged (still a static "..."). E-ink gets slower, coarser steps
(fewer, cheaper partial refreshes) than OLED; unchanged frames are
already skipped by the display's CRC diff, so idle holds are free.

Wired into every screen with a selectable row: home favourites, DM/
channel lists and message bodies, Settings, popup menus, Bot, Admin,
Nearby, Waypoints, Locator, Live Share, and the alarm screen.
