fix(cycle): use the shared query-error primitives on failed cycle reads

The cycle tabs rendered a bespoke error row in muted text, wrapped in a
bare card. Replace it with the shared primitives: QueryErrorCard on the
standalone prediction/insights/settings tabs, and a borderless
QueryErrorRow inside the calendar card so the failure reads as foreground
content with retry rather than muted meta. Test watched the muted row
first.
