dev2: per-proxy nginx locations; social.w3bs.org serves the Bluesky web client, PDS paths to the PDS

[ralyodio]

Adds an optional locations field to a proxies entry, inserted ahead of that host's location / (the same way nginx_locations works for the main site). w3bs.org uses it so social.w3bs.org serves the Bluesky web client (port 3343) while /xrpc/, /oauth/, /@atproto/, /.well-known/ and /account go to the AT Protocol PDS (port 3342). Already applied on dev2 with dev2-site vhost w3bs.org (dry-run first). App side: profullstack/w3bs.org#65.
