chore: comprehensive commit of all debugging, infrastructure, and extension fixes

Summary of changes:
- Corrected Directus extensions to use 'vue-router' for 'useRouter' instead of '@directus/extensions-sdk' (Fixed runtime crash).
- Standardized extension folder structure and moved built extensions to the root 'directus/extensions' directory.
- Updated 'scripts/sync-extensions.sh' and 'scripts/validate-extensions.sh' for better extension management.
- Added 'scripts/validate-sdk-imports.sh' as a safeguard against future invalid SDK imports.
- Integrated import validation into the '.husky/pre-push' hook.
- Standardized Docker restart policies and network configurations in 'cms-infra/docker-compose.yml'.
- Updated tracked 'data.db' with the correct 'module_bar' settings to ensure extension visibility.
- Cleaned up legacy files and consolidated extension package source code.

This commit captures the full state of the repository after resolving the 'missing extensions' issue.
