feat:refactor reserved keyword fields for discovery_upstream table. #6137
This PR refactor discovery_upstream reserved keyword fields by renaming two database columns in the "discovery_upstream" table to avoid reserved keyword conflicts. The changes rename "url" to "upstream_url" and "status" to "upstream_status". And fixed an error in tag-sqlmap.xml.

• Renamed database column "url" to "upstream_url" across all database schemas and related code
• Renamed database column "status" to "upstream_status" across all database schemas and related code
• Updated all corresponding Java entity classes, mappers, and service implementations to use the new field names
• fix an error in tag-sqlmap.xml, which would cause an error during unit testing.
