Pull Request Overview

This PR refactors the lock mechanism in NextcloudKit by changing from an object-oriented approach to a flattened property structure. The changes fix the interpretation of lock responses by properly handling numeric lock status values and making lock properties optional where appropriate.

• Changed lock representation from a single NKLock object to individual lock properties on NKFile
• Fixed lock status parsing to use integer values instead of boolean interpretation
• Made ownerEditor optional in NKLock to handle cases where it may not be present
