🛠️ [TASK] : MVE2 integration: give temp access to newly registered users

[mike-mcnulty]

Summary

give temp access to newly registered users

Description

As a user, I need temporary access to my account as soon as I submit a new role registration tx to chain, so that I do not need to wait for registration to be indexed / finalized on chain before I can start using the application.

GIVEN user is submitting initial role registrations
WHEN get success response from wallet extension
THEN post role0 key + staking address to backend with TEMP tag

Design Tasks

• Consider any user messaging needed about temp vs final access (eg anything in my account?)

Frontend Tasks

• Integrate with backend to post metadata at same time posted to chain

Architecture Tasks

• Define db design and labels to differentiate temp (internal only) vs tentative (on chain, not finalized) vs final (on chain, final) registrations
• Define expiration of temp registration
