Fix the issue that domain override has dependency on environment setting A365_OBSERVABILITY_USE_CUSTOM_DOMAIN

Pull request overview

This pull request fixes an issue where the domain override functionality (A365_OBSERVABILITY_DOMAIN_OVERRIDE) was dependent on the A365_OBSERVABILITY_USE_CUSTOM_DOMAIN environment variable. The fix extracts domain override logic into a separate function and checks it independently before falling back to other endpoint resolution methods.

Key changes:

• Extracted domain override logic into a new getAgent365ObservabilityDomainOverride() function
• Modified endpoint resolution to check domain override first, independent of custom domain flag
• Added test coverage for the scenario where domain override is set but custom domain flag is false

File	Description
packages/agents-a365-observability/src/tracing/util.ts	Refactored resolveAgent365Endpoint() to remove domain override logic and added new getAgent365ObservabilityDomainOverride() function to handle override independently
packages/agents-a365-observability/src/tracing/exporter/Agent365Exporter.ts	Updated endpoint resolution logic to check domain override first before using custom domain or discovery endpoints; renamed variable from endpointPath to endpointRelativePath for clarity
tests/observability/core/agent365-exporter.test.ts	Added new test case for domain override with custom domain flag set to false; updated test description and added assertion to verify tenant-id header behavior
