Service: harden for unattended running (auto-restart, findable logs, resume)

Local checkpoint - NOT for public release. A "what else does a service need" pass.

- AUTO-RESTART ON CRASH: DoInstall now sets sc failure actions (restart 5s/10s/then 60s,
  reset daily). Without this a crashed service stays dead until reboot - fatal for an
  always-on streamer.
- FINDABLE LOGS: --run-service redirects the service's data dir to the machine-wide
  ProgramData\RemSound\service location, so its log sits next to its profile instead of
  buried in the SYSTEM account's AppData.
- POWER RESUME: the service handles OnPowerEvent and re-opens capture on wake (audio
  devices re-initialise after sleep; the device-change watcher usually catches it, but a
  resume doesn't always fire an endpoint change, so we re-open explicitly).
- Start/stop already auto-log to the Windows Event Log via ServiceBase.

Test: "Service registration args" now also checks the audio-service dependency and the
auto-restart failure args. Gate 27/27.
