Description

• It fixes !35539
• Here is a brief description of what this PR does

Adding a tag using the rules engine is impossible when triggered with a self-service profile. This PR identifies tag addition by the rule engine and ignores the tag addition right of the triggering profile.

1. Test of the Rule Applying a TAG (Self-Service User)

   • Create a rule that applies a specific TAG to a ticket.
   • Simulate the creation of a ticket by a 'self-service' user.
   • Verify that the TAG defined by the rule is correctly applied to the ticket.

2. Test of the Rule Applying a TAG (Technician User)

   • Log in with a technician account.
   • Simulate the creation of a ticket.
   • Verify that the TAG defined by the rule is correctly applied to the ticket.

3. Test of Manual TAG + Rule-Based TAG

   • Log in with a technician account.
   • Simulate the creation of a ticket and manually add a specific TAG.
   • Verify that both the rule-based TAG and the manually added TAG are correctly applied to the ticket.
