freshrss: Add deploy script, context & classifier examples

FreshRSS was the only service with just a config.yaml: no auto-update
script, no instance context, and no review examples. That left the
classifier with no few-shot context, so every release would fall back
to "manual", and the auto-updater had nothing to run. These files bring
it in line with the other services so patch & feature releases can be
applied automatically while real breaking changes (volume path moves,
new required env vars) still surface for manual review.
