Channel page: fix re-poll never refreshing when recent videos collapse to one year

Browse source 
The date re-poll only re-rendered if the season COUNT increased — but for a
daily channel the 90 recent videos all land in the current year, so it went from
[2026(3), Earlier(87)] (2 seasons) to [2026(90)] (1 season): count dropped, so
the years (which WERE cached, per the logs) never showed and the spinner hung.
Now it re-renders whenever the 'Earlier videos' bucket shrinks too. Also extended
the poll window (20/45/80/120/160s) for channels queued behind others.
