Configure sentry_tracing event filtering

Import EventFilter and replace the plain sentry_tracing::layer() with a layer configured via .event_filter(...). The filter maps tracing levels to Sentry behavior: ERROR -> Event, WARN/INFO/DEBUG -> Breadcrumb, TRACE -> Ignore. This customizes which tracing records become Sentry events vs breadcrumbs (or are dropped) while keeping the existing tracing subscriber initialization.
