🟡 Changes recommended
The scalar comparison can select a value inconsistent with serialization and ignores longValue storage, causing filters to incorrectly exclude users with multiple stored values or attributes longer than 255 characters.

What changed in this PR
This PR addresses #53260 by aligning missing-value behavior for single-valued SCIM user attributes with direct entity fields.
Changes:
- Uses correlated scalar subqueries for single-valued collection-backed attributes while retaining
EXISTSfor multivalued attributes. - Adds regression tests for comparison, negation, and presence filters.
- Documents single-valued and multivalued negation semantics.

🟡 Changes recommended
Long-value comparisons remain inconsistent: attr ne "Engineer" excludes a user that not (attr eq "Engineer") includes because comparisons do not account for LONG_VALUE.

| For a single-valued attribute, the negated comparison `not (attribute eq "value")` behaves like `attribute ne "value"` | ||
| and also does not match resources where the attribute has no value. For a multi-valued attribute, | ||
| `not (attribute eq "value")` matches resources that do not have the given value, including resources where the | ||
| attribute has no value. |
