[Server] Serve password reset from the database interface (#7842)

cmdForgotPasswordRequest, continuePasswordRequest, cmdForgotPasswordReset,
cmdForgotPasswordChallenge, cmdRequestPasswordSalt and cmdSubmitPasswordVerifier
still called Servatrice_DatabaseInterface, and two of them validated the account
token and email through the generic validateTableColumnStringData helper. Add
doesForgotPasswordExist, addForgotPassword and getUsableLegacyBackup to
Server_DatabaseInterface with fail-closed defaults, replace the table/column
probes with userTokenMatches and userEmailMatches using the same statement and
case-insensitive comparison, and let the commands ask the injected interface.
Audit records, check order and every response code are unchanged.
