fix(Migration): Don't create empty notnull column

[marcelklehr]

fixes #1347

[Copilot]

Pull Request Overview

This PR fixes a database migration issue where a new column was being created with a not-null constraint without providing a default value, which would cause migration failures on existing databases with data.

• Changed the face_vector column creation to allow null values initially
• Added a subsequent migration to set the column to not-null after creation
• Improved migration logic to handle multiple column operations in a single migration
