Rekeyed account support

[kieranroneill]

Summary

Re-keyed accounts are a very core feature of AVM and are one of the final features of the Kibisis that must be implemented for Kibisis to be a fully compliant wallet.

This task sets up support for re-keyed accounts by displaying when an account is re-keyed, when the account is re-keyed without the auth account present (i.e. a watch account) and using the re-keyed auth account when signing transactions.

Acceptance criteria

Scenario 1: User sees a re-key account
GIVEN a User adds an account that is rekeyed with an account present in the account list
WHEN the User loads up Kibisis
THEN the a re-key badge appears on the re-keyed account in the side bar
AND a "Re-key" badge appears on the account page

Scenario 1: User sees a re-key account as a watch account
GIVEN a User adds an account that is rekeyed with an account that is not present in the account list
WHEN the User loads up Kibisis
THEN the a re-key account badge and a watch account badge appears on the re-keyed account in the side bar
AND a "Re-key" account badge appears on the account page with a warning
AND a "Watch" account badge on the account page

Notes

• Re-keyed accounts whose auth address is not present in the account list, or whose auth address is a watch account, MUST be treated as a watch account.
