Persist and display the applied CSS template name in the "Load CSS template" dropdown

What is the problem or goal you're trying to solve or accomplish?

When editing a dashboard, users want to quickly identify which CSS template is currently applied so they can confirm, change, or remove it. Right now, reopening Dashboard Properties → Styling shows the CSS code in the text area but leaves the "Load CSS template" dropdown blank, so there's no easy way to tell which template produced that styling — users have to eyeball the raw CSS and compare it against templates manually.

How are you solving it currently?

By manually comparing the CSS in the dashboard's text area against the CSS of each saved template to infer which one was applied. This is error-prone and gets worse as the number of templates grows.

What is your recommended solution?

Have the "Load CSS template" dropdown display the name of the currently applied template (e.g., "Soft Dark Theme") when the edit dialog is reopened, so users can identify the active template at a glance without inspecting the CSS.
