Merge user_profile into user table

[varmar05]

Note: based on order of merges #610 we need to update alembic migration hash to keep history linear

Pull request overview

This PR merges the former user_profile one-to-one table into the main user table to reduce query joins while keeping API responses structurally compatible via a User.profile compatibility shim.

Changes:

• Add a migration to copy receive_notifications, first_name, last_name onto user and drop user_profile.
• Remove the UserProfile SQLAlchemy model and update queries/schemas/controllers to read profile fields from User.
• Update tests and CLI commands to stop creating UserProfile rows.
