SLA service tags with the "contains" operator do not match any service when the value contains "_" or "%". Values without these characters match correctly. The "equals" operator also works correctly.

Steps to reproduce:
1. Create a service and give it a tag, e.g. tag "TEST_SLA" with value "TEST_SLA_A".
2. Create an SLA with a service tag: name "TEST_SLA", operator "Contains", value "TEST_SLA_".
3. Save the SLA and check the matching services: no services are returned.
4. Repeat with value "TEST" (no underscore): the service matches.

Result:
No services are matched when the contains value contains "" or "%". The same happens with a value like "TEST_SLA%".

Expected:
"Contains" should match underscores , so value "TEST_SLA_" should match service tags "TEST_SLA_A", "TEST_SLA_B", etc.

Notes:

• Affects Zabbix 7.0 (tested on 7.0.24) and current master (8.0).
• Root cause: in ui/include/classes/api/services/CService.php the LIKE pattern is built as
    REPLACE(REPLACE(REPLACE(UPPER(sst.value), '%', 'Unable to render embedded object: File (%'), '_', ') not found._'), '!', '!!')
    Escaping "Unable to render embedded object: File (" last duplicates the ") not found." characters introduced for "%" and "_", producing a broken pattern.
• Suggested fix: escape "!" first:
    REPLACE(REPLACE(REPLACE(UPPER(sst.value), '!', '!Unable to render embedded object: File ('), '%', ') not found.%'), '', '!')
