Implement automated dependency updates using Dependabot or Renovate

[AlAfiz]

Description

Manually tracking version updates for Next.js, Stellar SDK, and React is tedious. We need a bot to automatically draft PRs when new non-breaking versions are released.

Acceptance Criteria

• Configure dependabot.yml or the Renovate app.
• Set it to run weekly on npm ecosystems.
• Ensure it groups updates if possible to avoid spamming the PR board.
• Ensure the CI pipeline (Lint, Test, Build) runs automatically on these bot-generated PRs so developers can confidently merge them.

Technical Details

• For a monorepo, ensure the configuration correctly maps to the root directory where the master package.json or workspaces are defined.
