feat(repo): add owner display name field for repositories

Add OwnerDisplayName field to Repository model to allow custom display name for repository owner (e.g., "John Smith" instead of username). Used in license generation, social cards, and other public-facing contexts. Includes migration v368 to add column, UI in repository settings, and updates to license creation and social card rendering to use display name when available.
