"""Desktop cron ticker: every local profile's store must be ticked.

The desktop app pools per-profile backends and reaps them after ~10 idle
minutes, so a secondary profile's in-backend ticker dies with its backend and
that profile's cron jobs silently stop firing until the user next opens the
profile. The PRIMARY desktop backend outlives the pool, so its ticker must own
every profile's store — the desktop sibling of the multiplex-gateway fix for
#69377.
