jgrusewski 0ac8aeee52 refactor(common): make init_observability sync with optional OTLP endpoint
Remove unnecessary async from init_observability -- body was fully sync.
Change otlp_endpoint from &str to Option<&str> -- when None, OTLP layer
is skipped (fmt-only mode). Update all 8 service callers.
