pager: fix Enter not activating a focused non-composer widget

handleHwKey() treated "a textarea is bound to the on-screen keyboard"
as "we're editing a field", but showKb() binds the composer as soon as
a chat panel opens and never unbinds it just because nav focus moved
elsewhere in the same panel. So with focus on, say, the quick-reply or
emoji icon, Enter fell into the composer's submit/newline handling
instead of activating the actually-focused widget -- the rotary
encoder's short click worked because it bypasses this function
entirely (navPushTap(LV_KEY_ENTER) goes straight into the focus
group). Now only treated as editing when nav focus is really on that
field, mirroring the CAP_TRACKBALL boards' existing s_kbd_nav/
s_nav_ta_editing distinction for the same problem.
