Option discounts, POS swatch colors, and general bug fixes

Improvements

• You can now set a negative price on a pricing add-on, so options that simplify a product reduce the total rather than only ever increasing it.

• Color values created with the color picker are now shown as a colour tile in POS, matching uploaded swatch images, so mixed sets of colors and swatches look consistent to your staff.

• Once your store has been migrated to V2, the legacy V1 block is no longer offered in the Shopify theme editor, preventing an outdated block from being added to your theme by mistake.

• When editing options, validation messages now read "The Option name is required" and "The Option value is required", making it clearer which field needs attention when saving an option.

Bug fixes

• When converting an option with "Allow multiple selections" enabled to radio buttons, the quantity selector setting is now displayed as expected.

• Previously, when required options were applied to only some variants of a product, the remaining variants could not be added to the cart. This has been resolved, and every variant can now be added as normal.
