feat: Upgrade to Rails 7.0.8.7 + Ruby 3.3.6 + Node 20 + jsbundling-rails (#680)

## Summary
Major upgrade bringing Vulcan to modern Ruby on Rails stack with
improved performance and security.

## Changes
### Framework & Language Upgrades
- 🚀 **Rails**: 6.1.4 → 7.0.8.7
- 💎 **Ruby**: 2.7.5 → 3.3.6
- 📦 **Node.js**: 16.x → 20.x LTS

### Asset Pipeline Modernization
- Migrated from Webpacker to jsbundling-rails with esbuild
- Replaced Sprockets with Propshaft for asset management
- Converted all 84 Material Design Icons to Bootstrap Icons
- Fixed Vue 2 components with IIFE format for compatibility

### Bug Fixes
- Fixed OIDC cookie overflow by moving discovery cache from session to
Rails.cache
- Fixed component rules_count counter cache not updating after bulk
import
- Fixed ENV.fetch mocking issues in tests
- Improved ComponentCard UI and control count display

### Technical Improvements
- Updated all Rails JavaScript packages to v7
- Added REXML gem for Ruby 3.0+ compatibility
- Pinned concurrent-ruby to 1.3.4 to avoid Rails 7.0 Logger bug
- Updated GitHub Actions for Ruby 3.3.6 and Node 20
- Added SSL verification workaround for corporate proxy environments
(temporary)

## Testing
- ✅ All 198 tests passing
- ✅ RuboCop linting clean (33 pre-existing issues documented)
- ✅ ESLint passing
- ✅ Application tested locally with full functionality

## Known Issues (To Fix Post-PR)
1. Test suite is destructive when run in development mode
2. Overlaid components in seed data have 0 rules (should copy from
parent)
3. Dockerfile SSL verification disabled (needs proper certificate
configuration)

## Migration Notes
- Run `bundle install` after pulling
- Run `yarn install` for updated Node packages
- Run `rails db:migrate` if any pending migrations
- Clear browser cache if experiencing asset issues

Closes #670, #382
