- Render SessionBatchViewModel into NetCord EmbedProperties + ActionRowProperties
- One embed per session with game title, Moscow date, players, capacity, waitlist, status
- Buttons map AvailableAction to ButtonProperties with platform-neutral custom IDs
- Cancelled sessions get embed but no action row
- Full sessions trigger waitlist button label
- 7 tests covering open/full/waitlist/cancelled/reschedule states
Closes#27
