ots privacy section: capitalize Ordpool + reframe Cloudflare caveat

Brand name is 'Ordpool' (capitalized), not 'ordpool'. Domain stays
lowercase (ordpool.space).

Reframe the Cloudflare caveat: they're in front for caching and DNS,
not just DDoS protection. The CDN-metadata logging point stands either
way; the wording is just more accurate about what role they actually
play in the stack.

         One honest caveat: Cloudflare sits in front of ordpool.space for
