Fix demo-bot cron + cadence math
`*/90 * * * *` is invalid cron (minute field is 0–59) and degrades
to hourly, producing half the intended bot cadence. Switch to
`0,30 * * * *` (every 30 min) and lower the Bernoulli gate from
0.12 to 0.09 so we still hit ~2–3 walks/day during the 07–21
Berlin window.

* demo user's profile has content immediately.
* 3. Otherwise apply the decide-to-walk gate (local hour + p=0.09) and
* daily cap; on pass, insert one route+activity via `generateOneWalk`.
