feat(reactions): Move reaction settings to per-device profiles

Migrate reaction toggles (auto-play, auto-pause, auto-connect, popups) from global ReactionSettings singleton to per-profile fields on AppleDeviceProfile. Each paired device can now have independent reaction behavior.

Extract ReactionConfig snapshot to decouple PodDevice from AppleDeviceProfile — reaction consumers read device.reactions instead of device.profile. Remove auto-connect from upgrade benefits (now free). Add LegacyReactionSettingsReader for one-shot DataStore migration.
