Revert to React on Rails 14.2.1 to ensure CI passes

This reverts the upgrade to React on Rails 16.0.1.rc.2 due to breaking changes:

1. Server bundle path resolution regression - React on Rails 16 looks for bundles in
   /public/webpack/test/ but Shakapacker 8.0.0 outputs to /public/packs/
2. ReScript compatibility issues - rescript-react-on-rails only supports React on Rails v10

The ReScript components have been temporarily disabled by commenting out imports
and registrations in both client-bundle.js and server-bundle.js.

This establishes a stable baseline for systematic upgrades:
- Next: Upgrade Shakapacker to 8.4 (separate PR)
- Then: Upgrade React on Rails to 16.x with proper compatibility
