[Min/Max Quantities Edit Support] UI + Sync Logic

[toupper]

Closes: #12718

Description

With this PR we implement the edit support for Min/Max Quantities in the product and variations detail forms.

Testing instructions

Store without the Min/Max Quantities plugin installed. We don't show the Min/Max Quantities row in product and product variation details:

1. Go to a store without the Min/Max Quantities installed.
2. Open the app, and go to the products tab.
3. Tap on any product
4. You don't see any row about the Min/Max Quantities:

Store with the Min/Max Quantities plugin installed, but no values set in product. We show the Quantity Rules row with no rules:

1. Go to a store without the Min/Max Quantities installed.
2. Open the app, and go to the products tab.
3. Tap on any product
4. You see any row about the Min/Max Quantities row without any rule:

Store with the Min/Max Quantities plugin installed, and values set in product. We show the Quantity Rules row with rules:

• We show maximum two rows.
• Order priority is min, max group by.

Quantity Rules screen shows values and placeholder when there is none:

1. Go to a store without the Min/Max Quantities installed.
2. Open the app, and go to the products tab.
3. Tap on any product
4. Tap on the Quantity Rules row.
5. It opens the Quantity Rules screen with placeholders:

Edit Quantity Rules:

1. Go to a store without the Min/Max Quantities installed.
2. Open the app, and go to the products tab.
3. Tap on any product
4. Tap on the Quantity Rules row.
5. Edit Quantity Rules with happy path (valid values):

Product Variations:

We show the Quantity Rules row in product variations detail views if:

• The store has the Min/Max Quantities Plugin Installed
• The product variation overrides the parent quantities
• The parent product disables quantity rules

These two latter values can be set in wp-admin (Not in the app in this milestone)

1. Go to a store without the Min/Max Quantities installed.
2. Open the app, and go to the products tab.
3. Tap on any product with variations.
4. Tap on any variation.
5. Tap on the Quantity Rules row
6. You can edit the Quantity Rules

Errors:

We show the errors messages returned from the requests. These are

"woocommerce_rest_invalid_max_quantity"
"woocommerce_rest_invalid_min_quantity"
"woocommerce_rest_invalid_variation_max_quantity"
"woocommerce_rest_invalid_variation_min_quantity"

As these errors are dynamic, we can test if we show the right message by debugging the code or inspecting the response with Proxyman. You can test the behavior with inconsistent input:

• Min values bigger than Max
• Max values smaller than Mix
• Min Max values not in sync with group by (they should be multiples of the former)

Example: Entering a min value bigger than the maximum:
