Add account creation and approval workflow to create-a-container web server or homepage

[cmyers-mieweb]

Objective:

• Implement an account creation/sign-up tool inside the create-a-container web server, or on the opensource home page.
• Account requests should be forwarded to the devops inbox for approval before allowing new accounts to create containers.

Tasks:

• Design and build a user registration/sign-up UI integrated into the create-a-container web server or the main opensource site.
• Ensure account requests are sent to the devops inbox (e.g., via email or notification system) for manual approval.
• Block container creation for unapproved accounts; only approved accounts can create containers.
• Document the approval process and UX changes.

Priority: Medium

Acceptance Criteria:

• New users can request accounts through the web interface.
• Account requests are reliably forwarded to the devops inbox for approval.
• Only approved accounts are permitted to create containers.
• Documentation is updated to cover the workflow and approval process.

Going into cloudlfare and adding proper MX, SPF, DMARC, and DKIM records for the opensource subdomain. Installing postfix on the create-a-container LXC to server as a mail server. A form will be available for a user to fill out and that information will be emailed to devops to request the account. From then a member of devops will email back the client with the required information to get signed in for the first time once the account is provisioned.

This was implemented in a prior PR and is a redundant issue
