fix(RecentNotes): Prevent folder pages from always appearing first (closes #1901) (#1904)

* Fix(RecentNotes): Prevent folder pages from always appearing first

Pass prioritizeFolders=false to byDateAndAlphabetical in RecentNotes to sort strictly by date/alphabetical order, fixing issue #1901.

* refactor: split sorting functions for clarity

- Split byDateAndAlphabetical into two separate functions\n- byDateAndAlphabetical: sorts strictly by date and alphabetically\n- byDateAndAlphabeticalFolderFirst: sorts with folders first\n- Updated RecentNotes to use date-only sorting

* Fix(PageList): keep byDateAndAlphabeticalFolderFirst as the default sorting order for PageList
