feat(mikai,uaflix): implement voice-specific season filtering and redirect handling

Add support for restricting season lists by specific voice selection,
implement proper redirect handling when selected season is unavailable
for chosen voice, and add season set validation to ensure consistent
navigation between voices with different season availability
