Grafana: dashboard variable name not displayed but internal id is

### What happened? An example: dashboard with a variable name like DataSource is referenced in the text visualization in the content as ${DataSoruce} expected results should be the name of the data source string eg "sdhis2" but it looks like an internal ID is given eg "9UoKgKg7z" picture is a thousand words here <img width="1051" height="551" alt="Image" src="https://github.com/user-attachments/assets/1ae4d9f1-31aa-42fa-a68f-caf28e7d2cfb" /> ### What did you expect to happen? display "sdhis2" string variable inplace of ${DataSource} ### Did this work before? yes along time ago and as it was a small thing i was thinking someone else would notice and fix it. ### How do we reproduce it? 1.see screen shot above other or other palaces where ${var} is used like in table descriptions etc. 2. 3. ### Is the bug inside a dashboard panel? where ever ${} is used ### Environment (with versions)? Grafana: v12.2.1 OS: ubuntu container 20.04 Browser: edge ### Grafana platform? A package manager (APT, YUM, BREW, etc.) ### Datasource(s)? mssql or postgresql it doesn't matter.
