The DisableDockerUpdateActions setting was being saved to disk but not
updated in h.config, causing the UI toggle to appear to revert on page

Prevents multi-UID rate limit bypass attacks from containers. Previously,
attackers could create multiple users in a container (each mapped to
unique host UIDs 100000-165535) to bypass per-UID rate limits.
Implementation:
- Automatic detection of ID-mapped UID ranges from /etc/subuid and /etc/subgid
- Rate limits applied per-range for container UIDs
- Rate limits applied per-UID for host UIDs (backwards compatible)
- identifyPeer() checks if BOTH UID AND GID are in mapped ranges
- Metrics show peer='range:100000-165535' or peer='uid:0'
Security benefit: Entire container limited as single entity, preventing
100+ UIDs from bypassing rate controls.
New metrics:
- pulse_proxy_limiter_rejections_total{peer,reason}
- pulse_proxy_limiter_penalties_total{peer,reason}
- pulse_proxy_global_concurrency_inflight

The name "temp-proxy" implied a temporary or incomplete implementation. The new name better reflects its purpose as a secure sensor data bridge for containerized Pulse deployments.
Changes:
- Renamed cmd/pulse-temp-proxy/ to cmd/pulse-sensor-proxy/
- Updated all path constants and binary references
- Renamed environment variables: PULSE_TEMP_PROXY_* to PULSE_SENSOR_PROXY_*
- Updated systemd service and service account name
- Updated installation, rotation, and build scripts
- Renamed hardening documentation
- Maintained backward compatibility for key removal during upgrades
