feat: Add automatic Goose migration execution on startup in carrier-connector PostgresProfileStore

- Add os/exec import for running external commands
- Implement runMigrations function to execute goose postgres migrations
- Call runMigrations in NewPostgresProfileStore before returning store instance
- Update function comment to reflect automatic migration execution on startup
- Add error handling and output capture for migration failures
