Subject: [PATCH] Optimize
 OneNoteDataSource.me_onenote_notebooks_section_groups_sections_update_pages_content

The optimization achieves a **9% runtime improvement** by eliminating unnecessary object allocation during request configuration setup. Here are the key changes:

**What was optimized:**
- **Removed duplicate RequestConfiguration allocation**: The original code created two separate `RequestConfiguration` objects - one for `query_params` and another for `config`, then assigned the first to the second's `query_parameters` property
- **Direct config usage**: The optimized version creates only one `RequestConfiguration` instance and sets query parameters directly on it
- **Added defensive copying**: Uses `headers.copy()` to prevent accidental mutation of caller's input headers

**Why this improves performance:**
- **Reduced memory allocations**: Eliminates one unnecessary object creation (line profiler shows the second `RequestConfiguration()` call took ~1262.6ns per hit in the original)
- **Fewer object assignments**: Removes the `config.query_parameters = query_params` assignment step
- **Streamlined object lifecycle**: Single config object reduces garbage collection overhead

**Performance impact:**
The line profiler shows the optimization saves time in the configuration setup phase (lines creating and assigning RequestConfiguration objects), while the actual API call time remains unchanged. This is expected since the network I/O dominates execution time.

**Test case effectiveness:**
The optimization benefits all test scenarios equally since every call must build request configuration. The concurrent test cases (5, 50, and 100 operations) would see cumulative benefits from reduced per-operation overhead, though throughput remains constant at 1115 ops/sec due to network I/O being the bottleneck.

This is a clean micro-optimization that maintains identical functionality while reducing unnecessary object creation overhead in the request preparation phase.
