Add new DbSet properties to RecDbContext

Expanded RecDbContext to include new DbSet properties for
managing `Connections`, `Endpoints`, `EndpointAuths`,
`Profiles`, and `RecActions`. These additions enable
interaction with corresponding database tables/entities.

Updated the `OnModelCreating` method to ensure proper
configuration of the context. Removed an extraneous
closing brace to maintain proper syntax.
