feat(app): the recovery phrase's words typed back are suggested from BIP-39's list (ADR 0017)

Each of the three fields suggests the words of BIP-39's whole English
list beginning with what is typed, never the phrase's own, and refuses a
word not on it as its field is left, so that a typo is caught before the
words are compared.
