Events now come from EVENTS_FEED_URL (the scout-calendar container,
which serves Radicale mike/site73 as JSON). The last good copy is
cached to /data/events-cache.json and served whenever the feed is down
or empty; 'Nothing on the books' remains the cold-start floor only.
The round-trip test proved the feed reproduces all 32 rows of
app/events.json byte-identically, so nothing visible changes today.
Removes app/events.json, the first-boot seed copy, and the local load
path; README calendar section rewritten; compose gains EVENTS_FEED_URL
from the Portainer stack env.
