fix(tui): reduced row flicker while typing

Browse Source 
Changed text row repaints to overwrite first and clear only stale suffixes so non-synchronized WSL/Windows Terminal paints do not visibly blank already-rendered rows. Kept full-line pre-clears for image protocol rows and preserved exact-width row handling.\n\nFixes #2011
