BizCore v1.4 Complete Workspace Engine

WHY THIS RELEASE:
The previous Business Units page redirected to Companies when no company was selected.
This release fixes that flow. Clicking Open Company now selects the company and opens
its default workspace automatically.

INSTALL:
1. Take a full file backup and database export.
2. Upload this ZIP to /public_html/ceylongemx.online/
3. Extract and overwrite the included files.
4. Login as Super Admin.
5. Open:
   https://ceylongemx.online/update-1.4.php
6. Click Install v1.4 Update.
7. Open Companies.
8. Click Open Company.
9. You should be taken to Workspace Dashboard.
10. Use Workspaces to create and manage additional workspaces.

IMPORTANT:
- Existing database table business_units is retained internally for compatibility.
- The user interface now uses the name Workspace.
- business-units.php remains as a compatibility redirect to workspaces.php.
