Describe the bug:
When asking the assistant to extract data from an index with custom field names that require escaping it is using the wrong escape mechanisms.
E.g. site-name would require site-name but it uses "site-name"

Steps to reproduce:

1. Create an index with non standard field name mapping like "site-name" or "Total Bytes"
2. Ask the o11y AI assistant to analyze data thats in those fields.
3. Assistant will create wrong ES|QL and retries until it may find the right way

Expected behavior:

Assistant can create correct ES|QL also for non standard field names and execute the created query successfully.
