The register can't check a password it never sees, and should its
database leak, the verifier and the keys wrapped under the password fall
to guessing at Argon2id's cost (the second reading's M8). Devices now
refuse a new password shorter than 12 characters, counted as code points
once normalised (halkyon_keys' checkNewPassword), at sign-up, a reset
keeping the keys and a change alike, before anything is derived; the new
password's field says so, and the refusal has its own text (en, de).
Signing in takes any length, so a password set before keeps working.

An impostor instance refused; a lost authenticator's reset by the
recovery phrase; the password alone signing in once a reset took
effect, an authenticator set up first; starting an account's reset
without the phrase, and finishing one with new keys and a new phrase;
in the account section, removing an authenticator (a code, never the
last), new recovery codes, and a change of password refused for a wrong
current one.

password.setRecoveryKeys took a session and a TOTP code alone, so a phone
signed in with its authenticator beside it could set a phrase of its
holder's own and, through the phrase's reset, a new password, never
knowing the old one. It now takes the old password's SRP proof (from
beginChange, the caller's own) and a TOTP or recovery code, as changing
the password does: one owner proof for both (_proveOwner), forwarded by
members, asked for in the account section's New recovery phrase.

ADR 0017, step 3: widget tests driving the sheets as a person would,
on halkyon_app's fakes: signing in with a code (a wrong one refused
alike), an account never finished signing in with a code by mail and
setting up its authenticator (QR code, key, recovery codes saved), a
lost authenticator's reset, creating an account (the phrase shown and
three of its words checked before anything reaches the instance), the
recovery phrase getting back in, and the account section (a password
offered to someone anonymous; an authenticator added only with a code
from one before; the password changed).
