Wolt contact form, menu search and POSbistro deposits

What's new

• Wolt, Wolt Drive and Wolt Storefront: Support details include a Wolt Polska contact form, so staff can send a complaint from there

Fixes

• POSbistro: Refundable deposits stay on the order sent to the POS, so the amount matches the original order
• Menus: A modifier group cannot be saved when the minimum number of choices is higher than the number of active options, which keeps menu publishing working on Wolt, Bolt Food and Pyszne.pl
• Menus: Searching for items shows matching results again, including when a category is selected
