feat: add Discord link to footer social icons

[Varshinigurram]

Description

This PR adds a Discord social media icon and link to the footer alongside the existing Email, LinkedIn, X (Twitter), and GitHub links.

The Discord icon follows the existing footer styling, hover effects, spacing, and responsive design patterns to maintain visual consistency across the application. The link opens the official Discord community in a new tab, making it easier for users and contributors to connect with the project community.

• Added Discord icon to the footer social links section
• Added external Discord invite link
• Configured the link to open in a new browser tab

Hi @viru0909-dev
I investigated the failing checks on this PR and found that they appear to be unrelated to the changes introduced in this contribution.

Findings

• PR Size Labeler

  • Workflow successfully calculated the PR size (size/XS).
  • Failed with: Resource not accessible by integration (403).
  • This appears to be a GitHub Actions permission/configuration issue rather than an issue with the code changes.

• Frontend Tests

  • The failure appears to originate from existing workflow/test issues and not from the Discord footer link implementation.

• Backend Tests

  • The failure is unrelated to the footer enhancement and seems to be caused by existing repository test/workflow issues.

• Validate Environment Templates

  • No environment files or configuration templates were modified in this PR.
  • The failure appears to be unrelated to the introduced changes.
