…e on plugin-load miss (LoopKit#2469)

* Preserve persisted pump/CGM state when a plugin can't be instantiated

instantiateDeviceManagers restored a manager by assigning pumpManager/cgmManager
= the result of ...FromRawValue(...). When the plugin wasn't available in the
running build, that returned nil, and the nil assignment fired the didSet, which
wrote rawPumpManager/rawCGMManager = nil and DELETED the persisted state — so
launching a build missing a plugin permanently wiped the pod pairing (incl.
session keys) or CGM config.

Only assign when the manager instantiates; otherwise log and leave the saved
state on disk so a later build that includes the plugin can restore it.

* Wire pump BLE heartbeat to the CGM reading schedule

Send the pump a PumpHeartbeatRequest (last CGM reading date + expected reading
interval) when it must provide the BLE heartbeat, or nil when the CGM wakes the
app itself, via the new setBLEHeartbeatRequest API. The last-reading time is
refreshed after every CGM reading (processCGMReadingResult already calls
updatePumpManagerBLEHeartbeatPreference), so the pump's heartbeat cadence tracks
the actual reading schedule.
