Inline immediate_hydration_enabled? method

Remove the intermediate immediate_hydration_enabled? helper method from
ProUtils and directly use ReactOnRails::Utils.react_on_rails_pro? instead.
This simplifies the code by removing an unnecessary layer of indirection.

The immediate_hydration_enabled? method was just a wrapper that called
support_pro_features?, which itself just calls react_on_rails_pro?.

Changes:
- Remove immediate_hydration_enabled? method from ProUtils
- Update all callers to use ReactOnRails::Utils.react_on_rails_pro? directly:
  - render_options.rb: immediate_hydration method
  - helper.rb: redux_store method
  - controller.rb: redux_store method
- Update test mocks to stub react_on_rails_pro? instead of immediate_hydration_enabled?
- Remove unnecessary test stubs in render_options_spec.rb
