Added a new tree-store column (COL_UNDERLINE) for channel rows so the UI can track underline state per channel entry in the channel list model.

Browse Source 
Initialized each new channel row with PANGO_UNDERLINE_NONE so only the active channel gets emphasized.
Updated tree selection handling to remove underline from the previously focused row and apply PANGO_UNDERLINE_SINGLE to the newly selected row, creating a clear “currently viewed channel” indicator.
Bound the channel name renderer’s underline property to the new model column so underline changes are reflected immediately in the channel list UI.
