Tidy up wp-admin — take plugin vendors' upsells, promos and notices out of the flow

Sanitize invisible and control characters (zero-width spaces, BOM, bidi controls, C0/C1 controls, soft hyphens) out of posts, ACF fields and search terms, plus a WP-CLI command to clean existing data.

Completely disable comments: closes discussion everywhere, hides existing comments, and removes every comment surface from wp-admin, feeds, REST and XML-RPC.
