fix: update TUI description when job is started or created from gobfile

When the TUI opens and a job already exists without a description, the
description from gobfile was not being displayed. This was caused by:

1. EventTypeJobStarted handler not copying description from the event
2. CreateJob not emitting EventTypeJobUpdated when description changes

 ### Fixed
 
 - **Runs panel column misalignment**: Fixed status column padding using byte length instead of visual width, causing misaligned columns when Unicode status icons (✓, ◉, ◼) were displayed.
+- **Gobfile descriptions not displayed**: Fixed job descriptions from gobfile not appearing in TUI when job already existed without a description.
