[MIRROR] [s] Audits object say() uses to make handling text more safe (#7927)

* [s] Audits object say() uses to make handling text more safe (#61147)

Made all say()s deal with encoding, audited all uses of say() to prevent double encoding or like, manually inserting span().
I left some stuff without sanitize that only draws from the code, since it's hell to clean up otherwise. That
and I let admins do whatever the fuck they want
