Description

This PR fixes #4706 by replacing all references to the deprecated cloudcv.org domain with the active eval.ai domain throughout the codebase. The cloudcv.org website is no longer functional, causing broken links on the LinkedIn page, GitHub profile, and throughout the application.

Motivation and Context

Fixes #4706

The cloudcv.org domain is no longer active, which creates a poor user experience and makes it difficult for new users and contributors to find official resources or contact the team. This issue affects:

• User-facing website links in footers and headers
• Contact email addresses in multiple components
• Documentation and contribution guidelines
• Email sender configuration in production settings

Changes Made

Frontend (v2 & Legacy)

• Navigation & Footers: Updated website links in footer.component.html, dashboard-footer.html, and footer.html
• Auth Pages: Fixed links in auth.component.html and auth.html
• About Pages: Updated branding and links in about.component.html and about-us.html
• Community Pages:
  • get-involved.component.html - Updated 4 email addresses
  • get-involved.html - Updated 4 email addresses
• Privacy Policy: Updated 3 admin email references in both frontend versions
• Challenge Pages: Fixed contact emails in challenge management and settings components

Backend Configuration

• Production Settings (settings/prod.py): Updated DEFAULT_FROM_EMAIL from noreply@cloudcv.org to noreply@eval.ai
• Common Settings (settings/common.py): Updated ADMIN_EMAIL configuration

Documentation

• Hosting Guide (docs/source/02-for-challenge-hosts/hosting-guide/host-challenge.md): Updated 2 team email references
• Code of Conduct (CODE_OF_CONDUCT.md): Updated admin contact email

Email Templates

• Account Verification (apps/accounts/templates/account/email_confirm.html): Updated website link

What was NOT changed (intentionally)

• Test files with mock email data (in tests/ directory)
• Nginx configuration files (maintains backward compatibility)
• SSL-related comments in deployment scripts
• Copyright notices in LICENSE that reference CloudCV organization

Type of Change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation update

How Has This Been Tested?

• Verified all updated links point to accessible pages
• Confirmed email addresses follow the @eval.ai domain pattern
• Checked that no functionality is broken by these URL changes
• Validated that all user-facing text reads naturally with the new domain
