feat(activities): move Past pill to end of the temporal strip

Past used to live in the Filters collapsible — a dropdown row of its
own for a single boolean toggle. Hoist it onto the temporal strip
right after This month so it's discoverable alongside the time-window
pills without claiming any extra vertical space. Composes orthogonally
with the temporal pills the same way as before.

Drop the now-redundant past-count contribution to the Filters badge —
the pill carries its own pressed state on the strip.
