Describe the bug
filtering of cards is not as expected
Similar to https://github.com/nextcloud/deck/issues/2317#issue-705420020

To Reproduce
Steps to reproduce the behavior:

1. create some cards with different due dates
2. reload deck or use other browser
3. filter the cards
   4.1. Error; Next 24 hours doesn't show card with due date in 13 hour
   4.2. Error: Next 24 hours, next 7 days, next 30 days shows overdue cards
   4.3. just not like expected (confusing?): next 7 days, shows also card with "Next 24 hours, "

Reproduce the reported filtering behavior in the Deck interface using cards with overdue, 13-hour, and longer due dates; no source files or tests are identified in the issue. Trace the card-filtering entry point and add coverage for the stated ranges, ensuring overdue cards are excluded and selections are disjunct as described.
