Pull request overview

This PR fixes issue #37370 by properly handling uncorrelated parameterized collections in compiled queries. When a parameter collection is used in a query without any operation that provides type inference (e.g., comparison to a column), the code now falls back to applying the default type mapping instead of failing.

Key changes:

• Modified type mapping postprocessors to handle collections without inferred type mappings by applying default mappings
• Added test coverage for compiled queries with uncorrelated parameter collection expressions across all database providers
