[Shopify] Do not block shop disable, shop delete and company delete if webhook cannot be deleted in Shopify

[onbuyuka]

Problem

When disabling a Shopify shop or deleting a shop/company, if the webhook subscription cannot be deleted in Shopify (e.g., due to invalid API credentials, network issues, or the store being disconnected), the operation would fail with an error like:

Error(s) on Shopify:
"[API] Invalid API key or access token (unrecognized login or wrong password)"

This blocked users from disabling or deleting shops even when the Shopify store was already disconnected or inaccessible.

Root Cause

The DeleteWebhookSubscription function was being called directly, which throws an error if the Shopify API call fails. Additionally, even when using a [TryFunction] wrapper, there were two issues:

1. TryFunction return value not used: In AL, if a TryFunction's return value isn't consumed, it behaves like a regular method and errors are still raised to the user.

2. Database writes inside TryFunction: The ExecuteGraphQL function writes to the log table, which is not allowed inside a TryFunction when called from certain contexts (like page triggers).

Solution

1. Created a new wrapper codeunit "Shpfy Delete Webhook Subs." (ID 30458) that uses the Codeunit.Run() pattern instead of [TryFunction]. This pattern:

   • Catches and suppresses errors (returns false on failure)
   • Allows database write transactions inside the executed code

2. Updated TryDeleteWebhookSubscription to use this codeunit pattern and return a Boolean result.

3. Updated callers in ShpfyWebhooksMgt to properly consume the return value with if ... then; syntax.
