- Added route-aware head sampling for OpenTelemetry trace export. When `tracing_enabled` is on, agent firehose endpoints (osquery distributed read/write, orbit ping/config, device desktop/ping) are sampled at 0.1% by default, admin reads at 2%, and everything else (enroll, SCEP, MDM checkin, cron jobs, GitOps batch) at 100%. Liveness probes (`/healthz`, `/version`, `/metrics`) are dropped unconditionally.

- Added `GET`/`PATCH /debug/trace_sampler` (admin only, behind the existing `/debug` auth) for adjusting ratios or flipping a 100% `force_full` debug window at runtime. Each Fleet replica polls the new `trace_sampler_settings` row every 60 seconds and applies changes without a restart.
