feat: cost center filter

[anjusha12]

Feature description

This feature enhances the cost center search function by applying user-based filtering. It ensures that users only see cost centers they are permitted to access based on their assigned Bureau or Department.

Analysis and design (optional)

• The feature follows the user permission structure in Frappe to restrict cost center selection:
• If a user has permissions for a Bureau, fetches cost centers linked to the Bureau.
• If no Bureau permissions exist, fetches cost centers linked to the user's permitted Departments.
• A SQL query dynamically filters cost centers based on user permissions, ensuring only relevant records are shown.

Solution description

• Implemented a Frappe whitelist function get_cost_center_list to filter cost centers dynamically.
• Retrieves user permissions for Bureau or Department from User Permission.
• Uses Bureau DocType to fetch cost centers for Bureau users.
• Uses Department Cost Center to fetch cost centers for Department users.
• Constructs SQL query conditions to filter cost centers dynamically.
• Ensures that cost centers marked as disabled are excluded.
• Supports text-based search with partial matching (LIKE operator).

Output screenshots (optional)

Areas affected and ensured

• Cost center selection in forms where the Cost Center field is used.
• Filtering logic in cost center searches based on user permissions.
• Backend SQL query execution for cost center lookup.
