Set page to 1 on change to sort order

[theosanderson]

          Agreed that it would be nice to have page in URL - but important to _clear_ the page whenever one changes any of:

• sort order
• sort column
• search filters

I remember in a previous version, the page was kept in URL even after one changed sort order which was confusing. I was about to open an issue for that but realized it's no longer a thing on main (I must have looked at an old version, maybe the demo)

(I think this is still an issue on main)
