Fix native image hints for web support.

This commit adds a required native image reflection hint to allow Jackson object mapping to resolve and invoke the constructor of PageMetadata.
It also fixes an issue that surfaced after changing the bean constructor argument for SpringDataWebSettings leading to failures during the native compilation.

Closes: #3171
