fix: restore configured phone access on launch

[wolfiesch]

Outcome

Previously configured private phone access restarts automatically when the packaged desktop app opens. Setup now reports ready only after the gateway and local OMP runtime are healthy, and the phone instructions include iOS VPN On Demand.

Verification

• pnpm check
• pnpm test (70 files, 984 tests)
• pnpm package:mac:unsigned
• Packaged app relaunch restored the gateway in about 3 seconds
• Tailnet phone route loaded all 625 current sessions with no offline state

Pull request overview

This PR restores previously configured private phone access automatically when the packaged desktop app launches, and tightens the “ready” signal so it’s only reported after the gateway and local OMP runtime are healthy. It also updates phone setup instructions to include iOS VPN On Demand guidance.

Changes:

• Add a startup restore path for phone access and invoke it during packaged desktop app initialization.
• Update phone access health/ready evaluation to wait for a healthy gateway and to surface an error when Serve is configured but the local OMP runtime is unhealthy.
• Expand documentation and UI instructions with iOS “VPN On Demand” reconnect steps.
