fix(ui): replace dark green colors with standard theme colors (#285)

- Update light theme SUCCESS color from #009664 to #00967D (standard teal)
- Update light theme ERROR color from #B42828 to #D93D3D (standard darker red)
- Update light theme WARNING color from #B47800 to #C99A2E (standard darker amber)
- Replace dark green hints color in renderer with TEXT_DIM (#829AB1)

These changes align with the established color palette in cortex-core/style.rs
and cortex-tui/ui/colors.rs for better consistency across the UI.
