Templating: Prevent editing of templates and partial views in production runtime mode (closes #21564)

[AndyButland]

Description

This PR addresses #21564 which points out that we don't have the same behaviour in 17 as we do in 13 when it comes to surfacing information about templates and partial views being restricted for editing when running in production runtime mode.

The following updates are introduced:

• Prevents editing of templates and partial views when Umbraco is running in Production runtime mode.
• For templates: blocks create/delete operations fully; blocks content changes but allows metadata updates (e.g., name).
• For partial views: blocks all create, update, delete, and rename operations.
• Adds server-side validation at the service layer with appropriate operation status codes.
• Updates the backoffice UI to hide the save button, show a warning banner, and make editors read-only.

Change Details

Server-side

• Added NotAllowedInProductionMode status to PartialViewOperationStatus.
• Added NotAllowedInProductionMode and ContentChangeNotAllowedInProductionMode statuses to TemplateOperationStatus.
• Updated PartialViewService to check runtime mode and block modifications in production.
• Updated TemplateService to check runtime mode, blocking create/delete fully and content changes on update.
• Updated API controllers to return appropriate error responses for the new statuses.

Client-side

• Added IsProductionMode condition for workspace actions.
• Hidden save button in production mode via workspace action conditions.
• Added warning banner in template and partial view workspace editors.
• Set code editors to read-only in production mode.
• Disabled interactive buttons (insert menu, query builder, etc.) in production mode.

Tests

• Added integration tests for PartialViewService production mode behaviour.
• Added integration tests for TemplateService production mode behaviour.

UX

For the warning message, I couldn't find an existing example to copy styling-wise, so have used the available colour variables to make something that looks good (to my eyes at least).

However in FE review it could be you'll want to change this, either stylistically or to make consistent with some other similar informational label.

Testing

To set up for testing:

• Configure Umbraco:CMS:Runtime:Mode to Production in appsettings.json
• On start-up you'll likely get warnings about other things you need to do to run in production mode. If you want to avoid setting all that up, you can temporarily amend RuntimeModeValidationService.Validate to early return with validationErrorMessage = null; return true;.

Then you can check the following:

• Open template workspace - verify save button is hidden, editor is read-only, warning message displayed.
• Open partial view workspace - verify save button is hidden, editor is read-only, warning message displayed.
• Verify API calls returns 400 when attempting to create/update/delete templates or partial views. Here you can use a GET request to retrieve the details of the template/partial view, then a PUT to update and check the response. In particular note that for templates, updates are allowed unless there's an attempt to change the file content.

Normal editing should work when production mode is not enabled.

Pull request overview

Prevents editing of templates and partial views when Umbraco is running in Production runtime mode, enforcing restrictions both server-side (services/API) and client-side (backoffice UI), with added integration tests.

Changes:

• Add new operation statuses and enforce production-mode restrictions in TemplateService and PartialViewService (plus API error mapping).
• Update backoffice templating editors/actions to become read-only and hide/disable save and editing affordances in production mode.
• Add integration tests for production-mode behavior and extend repository tests around file writing behavior by runtime mode.
