fix(zoho-desk): only add the edition hint when Zoho's error indicates it

mapZohoWebhookError appended the "requires Professional edition or higher"
guidance to every 403, but a 403 can also mean a wrong org, a missing scope, or
a bad token. Gate the hint on Zoho's own errorCode / message matching the
permission/edition pattern instead of the bare status, so unrelated 403s surface
Zoho's real reason without the misleading suffix. Adds a test for the
non-edition 403 path.
