refactor(rubgram): replace archive/round/slip system with deleted+submit_day columns and month-calendar

- drop endgameArchive table, remove archive() function
- replace archived boolean with deleted on endgameSubmissions
- add submit_day timestamp column
- replace round-based slip manager with /rubgram/admin/calendar route
- add monthly jsonb column to endgameSettings for month checkmark toggle
- add toggleMonth server action with SimpleTooltip UI
- fix publicQueue SQL bug (ambiguous column reference + precedence)
- wipe() now sets deleted=true instead of round-based archive
- cancel() uses soft-delete (deleted=true) instead of hard-delete
- guard calendar page with adminCheck
- update count route to exclude deleted submissions
