Nearest next: drive to the closest job

A route planned at 7 AM ignores where the tech actually is at 2 PM. Nearest next is a switch under the Today picker that fixes that.

• On: the next job is the closest one to where the phone is now, like “Next: Grace, 0.3 mi”, and the list re-chains after every Done. Finished jobs stay on top in the order they were done; jobs without a placed address keep the office’s order at the end.
• Off (the default): the office’s route order shows exactly as before.
• Private: the phone’s position never leaves the phone for this. Addresses are placed through the same lookup the calendar’s Order the route uses.

The office still owns the plan; Nearest next just saves the miles between the plan and the day.
