Center the search box in the topbar

Search-wrap was pinned to the right edge with margin-left: auto.
With Focus chips and Mark-orphans gone from the topbar (previous
commit) it had room to breathe — switch to margin: 0 auto so the
flex's auto margins absorb leftover space symmetrically and the
search lands in the middle.
