Refactor for CrowdNode 3rd party integration

[jojobyte]

This is a massive refactor to fix the internal state of several components, which were not correctly updating/resetting when some dialogs would close, as well as to move contact creation/updating out of the dialogs so that we can programatically create a contact without user interaction.

This is particularly useful for creating a CrowdNode or Maya contact, where the user shouldn't need to know the Address/Contact information.

🛠 Guidelines to remediate hardcoded secrets

1. Understand the implications of revoking this secret by investigating where it is used in your code.
2. Replace and store your secret safely. Learn here the best practices.
3. Revoke and rotate this secret.
4. If possible, rewrite git history. Rewriting git history is not a trivial act. You might completely break other contributing developers' workflow and you risk accidentally deleting legitimate data.

To avoid such incidents in the future consider

• following these best practices for managing and storing secrets including API keys and other credentials
• install secret detection on pre-commit to catch secret before it leaves your machine and ease remediation.
