feat(tabs): add option to show open tabs across all collections

[celian-hamon]

Adds a beta preference (toggled in Preferences > Display) that keeps open tabs from every collection visible in the tab bar together, instead of hiding them when switching the active collection.

Closes #5070, closes #5807

Poem

Tabs now gather, collection-wide,
With saved drafts safely by their side.
Hotkeys dance from near to far,
Every open request a star.
One beta switch, and tabs unite.

- Around line 172-176: Update RequestTabMenu.handleCloseSavedTabs() to derive
saved-tab IDs from collectionRequestTabs rather than only collection.items,
resolving each displayed tab’s collection consistently with the other bulk-close
handlers so saved tabs from all displayed collections are included.
