Kano 22e1d93b39 Adds a new Odyssey map: Decrepit Shipyard (#21500)
## About PR

Adds an industrial themed away site for Odyssey scenarios. The map
starts with a shuttle, broken by a randomized destruction feature.
Actors or the crew may choose to repair it to make it fly once more

### Detailed Changelog
<details><summary>Details</summary>
<p>

- Added a new map_effect, randomized destruction. It comes with two
varieties and different impact ranges. The way it work is the effect
chooses a random amount of turfs in the area it's placed on, and calls
`ex_act` on applicable contents in the turf.
- Added unused sprites for low railing and documented relevant functions
in the existing code.
- Made it so when a railing has an open end that doesn't connect to
anywhere, it'll apply an end cap, making it look more smooth.
- Added ceiling lattices.
- Adjusted unit tests to avoid conflicts that may occur with ceiling
lattices.
- Fixed a bug where the Odyssey subsystem repeatedly added lastly loaded
z-level to the scenario z-levels, instead of all relevant levels to the
site. This was causing issues in Odyssey maps with shuttles.
- Fixed hydrogen tank not using its sprite. Also recoloured the tank to
match modern hydrogen canister colour.
- Fixed `/obj/machinery/door/airlock/maintenance` not using its intended
appearance.
