fix(bookmark-pdf): Improve page reference resolution and simplify destination handling
- Refactor findPageIndex() to use multiple resolution strategies (direct ref comparison, object number matching, string representation, numeric values)
- Add resolvedPageRef parameter to findPageIndex() for more efficient page dictionary matching
- Improve named destination handling to properly extract 'D' entry from dictionary-wrapped destinations
- Remove unnecessary resolveRef() call on destination arrays to preserve array structure integrity
- Pass resolved page reference to findPageIndex() for better accuracy in page lookup
- Simplify footer markup across multiple pages (add-stamps, bookmark, form-creator, json-to-pdf, pdf-to-json, table-of-contents) by removing redundant background color and grid layout
- Enhance error handling and logging for page reference resolution diagnostics
