Real 413 root cause on .116 and .228 turned out not to be the body-size
limit — their /etc/nginx/sites-enabled/archipelago was a stale regular
FILE, not a symlink to sites-available, so every nginx update since
someone froze the active config had been invisible to running nginx.
The /api/blob location, added at some point after that freeze, didn't
exist in sites-enabled, so every attachment upload hit nginx's default
1m client_max_body_size and returned 413 regardless of attachment
size.
Deploy now re-creates the symlink on every run: if sites-enabled is a
regular file or missing, we replace it with a symlink to
sites-available. Idempotent if it's already correct.
Also applied the fix live on all 4 fleet nodes — /api/blob now
responds 401 (session-auth required, as designed) instead of 413 on
2MB+ test uploads.
