The metrics tooltip on the Metrics page displays pod information incorrectly formatting and data issues 

 1. Navigate to the Observe -> Metrics page
 2. Hover over a data point on the metrics graph
 3. Observe the tooltip that appears
 4. Check the information on the tooltip     

    1. Empty/Missing Pod Information: A pod entries show empty or null values
  2. Curly Braces in Pod Names: Pod names are displaying with template syntax instead of clean values:
    - Showing: {{pod="alertmanager-main-0"}}
    - Expected: alertmanager-main-0

   - Pod names should display cleanly, and should not contain curly braces {} (e.g., "alertmanager-main-0")
  - Empty value should not appear in the list
