Widgets: align every widget to the exact logo palette (KC-19)

WidgetTheme now uses the true brand colors — accent RGB(232,98,42) on
the logo's dark RGB(26,29,34) — replacing a near-miss orange on slate.
Bars countdown, My Tasks, and Day Progress inherit it; Task Live
Activity drops its hardcoded accent/black tint for the theme; lock
screen rings tint brand orange.
