chore: DTOSS-12664 Filter health alerts from logging

[hardik-desai-nhs]

Description

This PR updates health-check telemetry filtering to reduce Application Insights noise while preserving error visibility.
This PR also Fixes Configuration Issues with Audit-Writer and Delete-Participant function apps
This PR also Standardizes the ServiceBus Connection String variable across azure, terraform, Docker, local.setting and various other places

Context

Health endpoint invocations were generating non-actionable Application Insights entries (request/trace/internal logs), creating noise.
The goal is to suppress routine health-check logs while still allowing exception/failure telemetry through for alerting and investigation.
