Fix broken pagination on tickler list view

[coderabbitai]

Description

The pagination on the tickler list view is currently broken. The system is loading all entries first and then paginating them client-side, which can cause performance issues with large datasets.

Current Behavior

• All tickler entries are loaded into memory
• Pagination is applied on the client-side after loading all data

Expected Behavior

• Pagination should be handled server-side
• Only the entries for the current page should be loaded

Will keep working on this for now as I have a Work In Progress on this from previous updates in the attached branch, but I can switch contexts as needed

Back working on this unless anything is found to work on
