Subject: [PATCH] fix(sim): live RTC restore + add
 sim_test_show_all_home_pages() hook

DataStore::restoreRTCTime() runs on every boot and, if a prior save
exists, overwrites RTCClock with that stale timestamp. Correct on real
hardware (no other way to know the time before a GPS fix or a phone/CLI
sync), but SimRTCClock is already backed by the real host wall clock from
construction -- overwriting it with an old IDBFS-persisted save made a
returning meshcore-solo-site visitor's on-screen clock drift away from
their own real time instead of just showing it. Guarded behind #ifndef
SIM_PLATFORM.

sim_test_show_all_home_pages() is a new sim-only test hook, same shape as
the existing sim_test_* hooks in this file: real hardware ships with a
curated 5-page Home carousel (NodePrefs::HP_DEFAULT) so a first-time user
isn't handed 13 pages to joystick through, with the rest opt-in via
Settings > Home Pages. meshcore-solo-site calls this once after boot to
show the whole feature set instead, without touching the real-hardware
default.
