Move Pro Ruby code to MIT license (#1855)

* Move Pro Ruby code to MIT license

Moved lib/react_on_rails/pro/ code to MIT-licensed locations:
- lib/react_on_rails/pro/helper.rb → lib/react_on_rails/pro_helper.rb
- lib/react_on_rails/pro/utils.rb → lib/react_on_rails/pro_utils.rb

Changes:
- Removed Pro license headers from moved files
- Changed namespace from ReactOnRails::Pro:: to ReactOnRails::
- Removed Pro warning badge functionality (no longer needed)
- Deleted lib/react_on_rails/pro/ directory entirely
- Updated LICENSE.md to reflect all lib/react_on_rails/ is MIT
- Updated documentation references

Benefits:
- Ruby signaling code now in MIT gem for marketing visibility
- Actual functionality still requires Pro npm package
- Clean license boundaries maintained
- Users can't bypass Pro features by editing Ruby code

* Remove Pro warning badge tests

Removed all test contexts for Pro warning badge functionality since
the badge feature has been removed from the codebase.

Tests removed:
- react_component Pro license warning contexts
- react_component_hash Pro license warning contexts
- redux_store Pro license warning contexts

* Revert previous two commits to preserve Pro warning badge

* Move Pro Ruby code to MIT license (preserving Pro warning badge)

Moved lib/react_on_rails/pro/ code to MIT-licensed locations:
- lib/react_on_rails/pro/helper.rb → lib/react_on_rails/pro_helper.rb
- lib/react_on_rails/pro/utils.rb → lib/react_on_rails/pro_utils.rb

Changes:
- Removed Pro license headers from moved files
- Changed namespace from ReactOnRails::Pro:: to ReactOnRails::
- PRESERVED Pro warning badge functionality (shows when Pro features used without license)
- Deleted lib/react_on_rails/pro/ directory
- Updated LICENSE.md to reflect all lib/react_on_rails/ is MIT
- Updated documentation references

Benefits:
- Ruby signaling code now in MIT gem for marketing visibility
- Pro warning badge alerts users about Pro features
- Actual functionality still requires Pro npm package
- Clean license boundaries maintained
