Rules can leave a manual pick alone, Clock is an editable page, fix HA attributes

- Rules: "also over a page chosen by hand" (on by default); off, a rule
  waits until the manual pick ends. Schedule store version 3, version 2
  records are read with the option on.
- The Clock page is stored at boot from the built-in one and can be
  edited; Reset (deleting it) brings back the original.
- Home Assistant attributes were never found: ArduinoJson 7.4 takes a
  char array key as a literal of its full array length.
