feat(fitness): label finish button "FINISH EARLY" with unfinished sets

Switches the active-workout finish button to "FINISH EARLY" /
"VORZEITIG BEENDEN" with an orange tint when any set in the workout is
still incomplete, so users can tell at a glance whether they're
wrapping up cleanly or cutting it short.
