feat: move filter chips to bottom of note list with gradient fade

Move FilterPills and InboxFilterPills from the top (below header) to
a floating position at the bottom of the note list. When position is
"bottom", pills are absolutely positioned with a gradient background
(transparent → card color) to create a "floating above content"
effect. Pills are centered with gap-2 and wrap to multiple lines.
Matches the ui-design.pen "Filter Pills Bar" frame.
