Replace the teleportation logic on the SCRAM implant! (#26429)

* Replace the teleportation logic on the SCRAM implant!

Now instead of just trying to pick a random tile in range 20 times, the
scram teleportation logic now:

- Gets a list of grids in range
- Until a suitable tile is picked it picks a random grid
- From that grid it picks a random tile.
- If the tile is suitable, then it is set as the target and the user
  will be teleported there.
- Grids and tiles are randomly picked as outlined above until a valid
  tile is found, or all valid grids and tiles are exhausted.
- Should no suitable tile be found then they get teleported to the same
  position they are at. Effectively not teleporting them.

* Actually make the defaults sane which I forgor in the last commit

* Extract tile section to its own function. Bias selection for current grid. Use proper coords for box.

* Address reviews as much as possible
