[v6][Bug] List view needs a little polish

I’ve created a new Users CRUD, and I’m looking at the ListOperation in Theme-Tabler and… the table looks a bit odd:

[x] The first heading row is not the same color as the last one
[x] The table uses 3 shades of grey (first heading row, odd rows, even rows)
[x] The heading texts don’t really stand out; the text is greyed out and yes it’s capitalized but… it’s smaller than the table body text;
[x] The “items per page” select looks unstyled;
[x] The next and previous buttons in pagination look like < and > texts, instead of carets (icons); but I guess it's ok, it's always been this way;
[x] The search bar isn’t rounded and... since it has no search icon either... it’s not intuitive that it’s a search bar; I suggest we round the corners;
[x] The search bar, when clicked, has a blue hue (not purple); this is true for all inputs on theme-tabler, and it bothers me; it doesn’t look intentional, but an oversight; actually I think ALL inputs have a blue blue instead of purple, when clicked - the CRUD fields too;
