Web GUI: Make thead sticky to the top

Hi, a small but quite nice improvement would be to make the thead (table head) sticky to the top, this keeps the column names in view when you scroll down a long table, like docker containers. The 'fix' is very simple and does not appear to introduce any UI issues:

thead {
  position: sticky;
  top: 40px; /* height of nav bar */
  z-index: 100; /* make sure it's always on top of table contents */
}

I put it in a user client css file like this for testing (or just apply the above styles to any of the <thead> elements):

body:has(unraid-i18n-host) thead {
  position: sticky;
  top: 40px; /* height of nav bar */
  z-index: 100; /* make sure it's always on top of table contents */
}

Cheers
