feat: Add workflow activation/deactivation via diff operations

Browse Source 
Implements workflow activation and deactivation as diff operations in
n8n_update_partial_workflow tool, following the pattern of other
configuration operations.

Changes:
- Add activateWorkflow/deactivateWorkflow API methods
- Add operation types to diff engine
- Update tool documentation
- Remove activation limitation

Resolves #399
