Allow custom admin username and email during install

The installer now prompts for and validates a custom admin username and email, updating migrations and SQL placeholders accordingly. Login now accepts either username or email, and the login form and installer views have been updated to reflect these changes. Additional logging and migration handling improvements were made for better installation and authentication workflows.
