Re-entries and lammers

[ctm]

Disallow the setting of the last re-entry level beyond the last lammer level.

Lammers are relatively rare, but they were actually used in the 2022 and 2023 WSOP short deck tournaments, both of which exist as structures in mb2. In both of those structures, both the last lammer level and the last re-entry level is level eight. Currently, the tournament creation UI allows people to change the last re-entry level and we typically set the last re-entry level to level nine for evening tournaments. That creates a problem that hasn't been hit (AFAIK), in that players can re-enter after lammer redemption.

I haven't even tested to see what happens if a player re-enters after redemption, but my guess is the player then gets two lammers which might not even be redeemable.

Lammer info is not currently configurable at the database level; it exists solely in the structures, which are currently hardcoded. So, although there are alternative solutions to the problem of having a re-entry after the mandatory lammer redemption, simply disallowing them at event creation is the easiest and is what should be done now.

I've done the work on the client side and will be deploying soon. I will add something on the server side before closing this issue.
