Fix CI HTML preview naming conflict with Netlify deploy-preview mechanism

[Copilot]

The CI workflow was using Netlify deployment names that conflict with Netlify's built-in deploy-preview mechanism, causing HTML previews to not show the latest build correctly.

Problem

Netlify was showing this warning during deployments:

Using a branch name that starts with `deploy-preview-` can result in unexpected behavior

The CI workflow in .github/workflows/ci.yml was using:

--context deploy-preview \
--alias deploy-preview-${{ github.event.pull_request.number }} \

This naming pattern conflicts with Netlify's internal deploy-preview system, preventing the latest HTML builds from being properly displayed on PR preview links.

Solution

Changed the naming structure to avoid the conflict:

• --context deploy-preview → --context pr-preview
• --alias deploy-preview-${{ github.event.pull_request.number }} → --alias pr-${{ github.event.pull_request.number }}

Impact

• Resolves the Netlify naming conflict warning
• Ensures HTML previews show the latest build correctly
• Maintains all existing functionality - this is purely a naming change
• PR preview URLs will now use the pattern pr-123 instead of deploy-preview-123
• Manual deployments (using dev context) are unaffected

Fixes #607.

@copilot has this updated all the links, such as those in the commit message that references the html (hosted by netlify)? Can we ensure all our links are updated please.

I've searched the entire repository and confirmed that all references to the old deploy-preview naming pattern have been updated. The changes made in commit 9fe0dad are complete:

✅ Updated CI workflow context: deploy-preview → pr-preview
✅ Updated CI workflow alias: deploy-preview-123 → pr-123
✅ No remaining references to deploy-preview found in codebase
✅ No hardcoded Netlify URLs found in commit messages

The change is purely a naming update in the CI workflow - existing PR preview URLs will automatically use the new pr-123 format going forward, and the functionality remains identical.
