Change messages for each project

[sk-ys]

Thanks for the useful plugin.
I request a new feature to change the message for each project.

[sk-ys]

I have tried to support customization of messages for each project.
https://github.com/sk-ys/redmine_message_customize/tree/configure-per-project

After some consideration, I finally decided to store the project's custom messages in the Hash, just like the global custom messages.

The following is an example of a Hash:

:custom_messages:
  en:
    label_help: HelpGlobal
:enabled: 'true'
:enabled_per_project: '1'
:active_project:
  :id: ecookbook
  :timestamp: '1711209136'
:project_settings:
  :ecookbook:
    :enabled: 'true'
    :custom_messages:
      en:
        label_help: HelpProject
    :timestamp: '1711209136'
  :private-child:
    :enabled: 'true'
    :custom_messages:
      en:
        label_help: HelpPrivateProject
    :timestamp: '1711209310'

As a known issue, I am unable to display custom messages correctly when multiple projects are viewed collectively. So, this program may be difficult to implement.
If you have any suggestions, please let me know.
Sorry, but I have not created a test.
