Update a mounting colour

Applies an RFC 7396 JSON Merge Patch to one mounting colour: properties omitted from the body are unchanged, and `null` clears a nullable property (`description`, the minimum sizes). Arrays are replaced wholesale, so sending `mounting_ids` replaces the whole list. Read-only and unknown fields are rejected. An empty object `{}` is a valid no-op. Requires `customisers:write`. `hexcode` and `opacity` are two views of one stored colour, so a patch naming either keeps the other. The colour cannot be cleared and `mounting_ids` cannot be emptied: either would leave a colour the storefront never shows. An `Idempotency-Key` is optional here: sending one makes the update safe to retry (an exact repeat replays the original response; the same key with a different body is a 409). The update clears the customiser's cached storefront configuration and runs the advisory language sync, and never regenerates Shopify products, product images, or the product cache.

Overview

Read-only and unknown fields are rejected. An empty object {} is a valid no-op. Requires customisers:write. hexcode and opacity are two views of one stored colour, so a patch naming either keeps the other. The colour cannot be cleared and mounting_ids cannot be emptied: either would leave a colour the storefront never shows. An Idempotency-Key is optional here: sending one makes the update safe to retry (an exact repeat replays the original response; the same key with a different body is a 409). The update clears the customiser's cached storefront configuration and runs the advisory language sync, and never regenerates Shopify products, product images, or the product cache.
