## About The Pull Request

Reworks a lot of the wiring on Endeavor. A lot of the work is just
making it look nice and ensuring all wire junctions are oriented the
right way (following any wire from an APC and going in the natural
seeming direction will take you to the power source). Some areas like
starboard dorms didn't have power, I wired them up. A few breakers were
moved/removed as needed for the ship to function right. The Main SMES
was changed from something better than you can build to being a normal
Main SMES but with half the starting charge since this ship is designed
to use the Secondary Supply SMES for its starting power rather than
Main. There was also some shifting of things from one grid to another,
e.g. security was moved from the D3 midship grid to the D3 aft grid
since it's in the aft of the ship.

Also sets up the atmos machinery (filters, airmix to distro pump, etc.)
to run at a basic level roundstart like on other maps.

## Why It's Good For The Game

Proper wiring makes troubleshooting power issues easier. Having power in
all areas is good. Having air circulating is good.

## Changelog

<!-- If your PR modifies aspects of the game that can be concretely
observed by players or admins you should add a changelog. If your change
does NOT meet this description, remove this section. Be sure to properly
mark your PRs to prevent unnecessary GBP loss. You can read up on GBP
and it's effects on PRs in the tgstation guides for contributors. Please
note that maintainers freely reserve the right to remove and add tags
should they deem it appropriate. You can attempt to finagle the system
all you want, but it's best to shoot for clear communication right off
the bat. -->

<!-- You can use multiple of the same prefix (they're only used for the
icon ingame) and delete the unneeded ones. Despite some of the tags,
changelogs should generally represent how a player might be affected by
the changes rather than a summary of the PR's contents. -->
