Removes icons next to title in run and editor (#1478)

## Description

Removed unnecessary icon imports and their usage from the PipelineDetails and RunDetails components. Specifically:

- Removed the Network icon and its rendering from PipelineDetails
- Removed the Videotape icon and its rendering from RunDetails

Do we actually need these? I personally think no icon is cleaner. Also this section has a lot of information already, so adding in this visual flare seems a little too much.

## Test Instructions

Verify that the Pipeline Details and Run Details pages display correctly without the icons that were previously shown next to the pipeline/run names.

## Additional Comments

This change simplifies the UI by removing decorative icons that weren't adding significant value to the interface.
