Upgrade Rails to 8.1.3

[Copilot]

Updates the app from Rails 8.1.2 to the latest 8.1 patch/security release, 8.1.3. This refreshes the Rails framework version constraint and the locked Rails component versions without changing the JS dependency surface.

• Dependency update

  • Bumped the Rails gem constraint in Gemfile from ~> 8.1.2 to ~> 8.1.3
  • Updated Gemfile.lock so all Rails framework gems resolve to 8.1.3 (actionpack, activerecord, railties, etc.)

• Package manifest review

  • Reviewed package.json for a Rails-specific version pin
  • No change was needed there because Rails is not versioned through the Node manifest in this repo

• Documentation

  • Updated the README’s framework version reference from Rails 8.0 to Rails 8.1 to match the current app baseline

# Gemfile
-gem 'rails', '~> 8.1.2'
+gem 'rails', '~> 8.1.3'
