Fix: Reorder Entity properties to match JSON schema for stable serialization

- Reordered Entity.cs properties from (GraphQL, Rest, Mcp, Permissions) to (Rest, GraphQL, Mcp, Permissions)
- Updated constructor parameters to match property order
- Fixed test files using old constructor parameter order
- Accepted snapshots with corrected property ordering

This ensures System.Text.Json serialization produces consistent output, preventing
snapshot test failures in pipelines where deserialization-reserialize cycles would
produce different property ordering.
