Fix ProxySQL rule sanity check to support username-based routing

Kolla Ansible now generates ProxySQL query rules not only based on
the schema name (schemaname), but also on the username. This is
needed to properly route queries that are executed before a database
schema is selected, such as `SET AUTOCOMMIT` or `ROLLBACK`.

To support this, the ProxySQL config sanity check must correctly
deduplicate rules based on both `schemaname` and `username`, and
avoid false positives when both types are used simultaneously.

This change adjusts the logic in `kolla_proxysql_config_sync` to:
- recognize rules by key `schema:<schemaname>` or `user:<username>`
- assign unique rule IDs only to truly distinct rules
- log and skip exact duplicates with appropriate context

This fix is required to support the Kolla Ansible patch below.
