The verbose toggles (MPV, remote control) kept working with the master
"Enable Logging" toggle off: the settings UI hides them, but their
stored values - verboseMPVLogging is even iCloud-synced - were still
honored at runtime, producing console output and enabling the periodic
MPV stats collection while logging appeared disabled.
Enable Logging now takes precedence everywhere:
- LoggingService gates its DEBUG-build OSLog console output on the
master toggle (it previously ran before the isEnabled guard, so the
Xcode console was never silent)
- MPVLogging requires loggingEnabled && verboseMPVLogging, which also
gates the 10s playback stats task via MPVLogging.verboseEnabled
- rcDebug in LocalNetworkService and RemoteControlCoordinator requires
the master toggle alongside verboseRemoteControlLogging
