feat: add Clone Database to Docker functionality

Clone any database to a local Docker PostgreSQL container with schema
and/or data transfer via pg_dump. Supports three modes: schema only,
full clone, and sample data. Includes container lifecycle management
(start/stop/remove) in the Admin panel, progress tracking with
collapsible process log, and automatic connection creation.
