chore: remove dangerous migration scripts and clean up code formatting

- Remove migrate-active-identity-components.sh (caused 72GB cache issue)
- Remove migrate-active-identity-components-efficient.sh (unsafe bulk operations)
- Clean up code formatting in activeIdentity.ts table definition
- Standardize quote usage and remove trailing whitespace

These scripts were dangerous and created excessive disk/memory usage.
Manual, focused migration approach is safer and more reliable.
