Fix inconsistent date filtering

Ensured date filter logic is consistent across "All articles" and "Followed feeds only" modes in `src/hooks/useRealArticles.tsx`. Articles are now displayed correctly based on the selected date filter, or all articles are shown when no date filter is active. Debug logs were added to trace filter application and state management was verified to ensure proper filter resets between modes.
