[BUG] Add support for searching pages as core Foundry Journals

[LeCuay]

Describe the bug Foundry Journals have support for searching pages but this functionality seems to be lost when using Enhanced Journal.

To Reproduce Steps to reproduce the behavior:

1. Have a Journal with pages or a compendium with such a Journal (e.g. Pathfinder 1e Statblock Library)
2. Deactivate Enhanced Journal and use the Search Pages bar to see the filter working.
3. Activate Enhanced Journal and
4. See error

Expected behavior Since this is a core feature for Foundry I think it should be available within the module.

Please complete as much of the following information as possible:

• Application, Firefox, Chrome
• Foundry Version v11 build 315
• System Pathfinder 1e
• Module version 11.09
• Are there any errors in the console [e.g. press F12 and look for red text] Not related to the module (ITEM.AttackType deprecation and similar).
• Using the module alone raises same issues.
