Subject: feat(immich): fall back to the past week's memories

A day with no memories left the card showing only a notice. When today
has none, immich-fetch.sh now merges the memories of each of the past
six days, skipping a day whose request fails, and marks the index with
a scope week line. The subtitle names where the photos come from,
Today or This week, before the i/n counter, and the empty notice reads
no memories this week.
