0.19.8 Filter contract bundles by member

List contract bundles (GET /contract-bundles) now accepts an optional userId query parameter to return only the bundles that include that member:

GET /api/remote-health/v1/contract-bundles?userId=200345

• The filter matches against all members of a bundle — the policyholder and every dependant — so passing a dependant's userId returns the bundle covering them.
• Use the userId values returned in application-bundle and contract-bundle responses.
• Combines with the existing companyContractId, page, and size parameters.
• An unmatched userId returns an empty page (totalElements: 0); note that the data field is omitted from the payload when there are no results.

No changes to existing behavior — omitting userId returns the full listing as before.
