Add DbSets and configure keyless entity in RecDbContext

Added `HeaderQueryResults` and `BodyQueryResults` DbSet
properties to the `RecDbContext` class for interacting
with `HeaderQueryResult` and `BodyQueryResult` entities.

Overrode the `OnModelCreating` method to configure the
`RecAction` entity as keyless using
`modelBuilder.Entity<RecAction>().HasNoKey()`.
