Add title property to user

[tjementum]

Summary & Motivation

Add User.Title to the database, including updates to database migrations, DTO, UserRepository.Search, and database seeding.

Remove all usages of [UsedImplicitly] attributes, which were previously used to avoid warnings in JetBrains. These leftover attributes have been removed from Domain Entities and Developer CLI commands.

IMPORTANT: This change requires the existing database to be updated manually.
