[andrey-eysmont]

Update notes

This is a Localizable plugin of version "0.4.0" updated with SouthBridge.

Compatibility: Redmine 6.1 / Rails 7.2 / Ruby 3.3

Redmine 6.1 compatibility:

• fix view hooks logic for name_in_english field

Rails 7 autoloading compatibility:

• Removed deprecated require_dependency calls
• Replaced with require_relative inside Rails.configuration.to_prepare block
• Removed ActiveSupport::Dependencies manipulation code

Modern Ruby/Rails patterns:

• Refactored from include + alias_method pattern to prepend
• Changed patch application to after_initialize for proper loading
• Updated all model patches (Role, Tracker, IssueStatus, CustomField, Enumeration, User)
• Removed unnecessary # encoding: UTF-8 comments (UTF-8 is default in Ruby 3.3)

Testing:

• Plugin tested with Redmine 6.1, Rails 7.2, Ruby 3.3.10
