Make GITEA_SSH_HOST/GITEA_API required env vars, fetch inline review comments

Addresses PR #1 feedback: host config should live in the environment
(~/.profile.local), not be hardcoded in the script, with a clear error
if unset. Also fixes gitea-pr comments to surface inline diff comments
from reviews, not just issue comments and top-level review bodies --
the review that requested this change would have been invisible to
gitea-pr comments without this fix.
