refactor(core): Enable Systemd and upgrade Sentinel service orchestration

The legacy crontabs have been superseded by Systemd to fortify orchestration of our global fleet of Sentinels.

While cron relies on timed, fire-and-forget execution, Systemd elevates our operations into natively integrated, state-aware OS daemons. This paradigm shift unlocks precise lifecycle management, unified logging (inspect all service logs with `journalctl -t ip-sentinel`), and absolute control over module deployment.

- Battle-Hardened: Sentinels now auto-resurrect upon failure, bypassing minute-long cron wait times.
- Zero-Impact Missions: Sentinels now operate under strict `idle` CPU/IO scheduling. This guarantees that automated maintenance cycles yield to high-priority user interactions, and never impact primary server workloads.
- Field Intelligence Auto-Stagger: Service-level `RandomizedDelaySec` natively staggers Agent check-ins to protect the Command Center.
- Legacy Fallback: OS interrogation on deployment ensures a seamless fallback to cron for Sentinels operating in Alpine/OpenRC environments.

The fleet is more resilient than ever, but the architecture is always evolving. I highly welcome any reviews/suggestions from the original Author/Commander to perfect this pull request!
