v1.1.0.3 Bar fix

Issue: Orientation only affected solid bars. Segmented and trapezoid always drew horizontally, so Vertical in the property panel had no effect for those styles.

Changed

• Normalized orientation and style with .lower() so values like "Vertical" still match.
• Solid (vertical): Unchanged behavior; track full size; fill grows from the bottom upward (y + h - fh).
• Segmented (vertical): Segments stack bottom → top; lit count fills from the bottom (same percent logic as horizontal).
• Trapezoid (vertical): Full trapezoid track; fill clipped to a bottom-up height band so progress still reads correctly on a tall, narrow bar.
• Horizontal paths for all three styles left as before.
• Shared setup_indented for gradient/source setup inside segmented loops (avoids duplicating the replace logic).

Unchanged

• Node spec (visuals.py): orientation enum horizontal | vertical already present.
• Horizontal solid / segmented / trapezoid drawing.
• Gradient / blend pipeline via fill_source_lua.
