Save bar support, smoother editing and general bug fixes

Improvements

• We've added support for Shopify's App Bridge Contextual Save Bar on the pages where we can create or edit an option. Now, if you try to leave with unsaved changes, you’ll get a reminder, helping you to avoid losing any work.

Bug fixes

• We fixed a bug where reopening an option after navigating back to its option group caused the values and advanced settings to disappear. Everything now shows up properly without needing a refresh.

• Opening an option and returning to the option group without editing no longer hides the other options. Everything now loads as expected right away.

• Previously, typing Chinese characters into the 'Large text box' option on POS would only save the first character entered. This has now been resolved and all characters are saved.
