Fix trash page pagination

[ozer550]

Summary

• Cleared the trash Vuex cache and reset pagination flags, so reopening the modal always starts from page one.

References

• closes Hotfixes - Channel trash - Closing the Trash modal doesn't reset the pagination state #4851

Reviewer guidance

• Delete a large number of resources and open the channel's Trash page
• Clicking several times on 'Show more' works now with proper pagination.
• Close the modal and reopen it
• It still works with pagination getting reset.

I'm seeing that newly deleted nodes end up at the end of the trash list, when they should be at the top. I do not observe this on production, so it feels like it must be related to these changes.

After deleting Sparkfun-RPi5, it appeared at the bottom. A clue to the issue might be the modified time, for when it was deleted, because that isn't correct. After refreshing the page, the order is correct.
