Subject: [PATCH] feat(makhno): enhance season template generation with
 voice-specific filtering

Implements dynamic season template building that respects voice-specific
season availability. Adds proper handling of voice indices and creates
filtered season lists based on available content for each voice option.
This ensures season navigation remains synchronized when switching between
different voice tracks with varying season availability.
