Module reward 

Era reward management.

Manages the lifecycle of era reward pot accounts: creation, funding via snapshot from the general DAP pot, and draining of expired eras.

Era pots are backed by a rotating pool of POT_POOL_SIZE accounts addressed by era % POT_POOL_SIZE. Once created, a slot’s account is kept alive forever — at the end of each era’s history window, its remaining balance is drained to crate::Config::UnclaimedRewardHandler but the provider reference is retained. A future era that reuses the same slot finds an existing zero-balance account and snapshots into it. This bounds the storage footprint contributed by era pots to a constant.
