Auto mission names are not being shown into telemetry logs and video filenames

The auto generated mission names like "Venturing into the Vortex" and "Embarking on Neptune's Quest" are not being displayed on the subtitles telemetry overlay or on the video filenames. Instead, the word cockpit is being used when the user does not define a mission name.

Trace the code paths that generate the subtitles telemetry overlay and video filenames, then compare their fallback handling when no user-defined mission name exists. Verify the auto-generated mission name is used in both outputs instead of "cockpit"; no specific files or tests are identified in the issue.
