Fix avatar menu's missing border and put the tab title beside search

- The avatar menu card's border was going missing wherever an opaque
  row sat against it (every corner but the header's) - a Container
  combining `border` with its own `clipBehavior` paints the border as
  part of the outer decoration, then the clipped child on top right up
  to the same boundary, with no gap for the border's stroke to show
  through. Fixed with the standard pattern: no clipBehavior on the
  bordered Container, a 1px-inset ClipRRect around the filled, clipped
  content instead.
- NooTopBar.androidTitleTrailing (renamed from androidTitleReplacement)
  now sits beside the tab title instead of replacing it - the title
  keeps its natural width (Flexible, ellipsizing only if truly out of
  room) with the inline search bar taking the remaining space to its
  right, rather than the title disappearing whenever search moves into
  the top bar.
