fix(docking): make workspace and lid transitions atomic

Restore the old flake's external-only workspace handoff, protect closed-lid cable removal with a verified low-level logind inhibitor, and use monitor-added as the settled audio reprobe boundary.

Verified: V2 — nix flake check --no-build; docking-ux, option-docs, and template-sot checks; KVM tools/monitor-fallback.nix lifecycle test.

V3 pending: closed-lid BenQ round 4 in agent/HARDWARE-QUEUE.md.
