Release notes:

What's Changed

Azure Health Data Services (SQL)

• Search params concurrency ADR by @SergeyGaluzo in https://github.com/microsoft/fhir-server/pull/5459

Common to both Azure API for FHIR and Azure Health Data Services

• Fix concurrent collection access errors by @fhibf in https://github.com/microsoft/fhir-server/pull/5466: Previously, users could experience intermittent failures as a side-effect of background in-process attempts to update the capability statements. This issue is fixed by ensuring that access to the resources of the capability statement are using thread-safe components to help prevent these errors.
• Batch oversized bulk operation audit logs by @Copilot in https://github.com/microsoft/fhir-server/pull/5484: Previously, some bulk delete audit logs could exceed the maximum body size, preventing their processing. This issue has been fixed by splitting the items into size-bounded batches.
