feat: replace the preset gallery with original schedules

Swap the six suggested rules for an original set so the preset offerings
are OpenAppLock's own:

- Focus Time: Morning Focus (08:00-11:30 weekdays), Deep Work (13:30-16:00 weekdays)
- Rest & Recharge: Evening Reset (21:00-23:00), Lights Out (23:00-06:30, crosses midnight)
- Healthy Balance: Family Dinner (18:00-19:30), Screen-Free Sunday (09:00-20:00, Sundays)

Update the spec preset gallery (sections 1, 3.3, 4) and the preset
unit/UI tests to the new ids, names, and times. Build green; the preset
draft unit test and the two preset UI tests pass.
