fix: restore green/orange status colors for done/waiting

The redesign moved statusDone to emerald (#34D399) and statusWaiting
to rose (#F87171), which read as colder/redder than the original
system green + yellow. Switch to a saturated green (#22C55E) and a
clear orange (#FB923C) so the notch pill again reads at-a-glance:
amber = working, orange = needs you, green = done.

Tab bar status indicators pick up the same tokens.
