feat: About Us boards, Mr Mohammadi guide and products-hall orders

- Information boards in the factory yard (about, contact, address) painted from the
  company config; E opens the same sections the start screen shows.
- Mr Mohammadi welcomes the family at his desk on every visit with the company story;
  meeting him is a mission step.
- Products hall gets a purchase-request button and a sales contact link.
- New missions: About Us tour (read, meet, read) and products tour (view, ask, request).
  The About and Products start modes lead with their tour.
- Factory points share the station shape so the arrow, route and chip point at them.
