Patch Notes: Recovery codes in your profile

Accounts

Eight recovery codes instead of one. New accounts get a set of 8 recovery codes. Each code works once, if you forget your password.
See your codes in your profile. The Account section shows how many recovery codes you have left. Make new codes gives you a fresh set: type your password and one of your current codes. Your old codes stop working.
Copy or save them. When codes are shown you can Copy them or Save as a file (dfo-recovery-codes-<username>.txt).
Never left with none. Using a code spends only that code. Using your last one gives you a fresh 8.
Safer: someone who learns your password alone can't replace your codes, so your codes can always take your account back.
The codes screen can't be closed by accident (no Close, Escape or tap outside) until you confirm you've written them down.
Older desktop builds keep working as before, with one code.

RECOVERY-SET + AUDIT RECOVERY-SET: eight recovery codes, each spent alone, and a new set from the profile behind the password and one code by @Lattymoy in #892
