Morphia call fixes; add `@Entity` to more classes

1. During the conversion of Morphia calls to the new API, some of the `Filter.eq()` calls had their `field` set to `playerId` due to a copy/paste typo.

2. Morphia 2 switches to the codec system, so anything that will be serialized in the pipeline requires the `@Entity` annotation.
