LV522: Moves breaching charge again, buffs sec armoury as optional lo…

…ot area for FORECON, adds missing warning stripes (#3742)

# About the pull request

In my last PR I moved the breaching charge because I thought it's prior
location was too "free" for FORECON the location I moved it was too far
away off the beaten path for FORECON making it entirely useless this PR
moves it back onto the path while still being something they have to
trek for it's also been made unacidable due to the location it's been
moved to
(The APC north of fitness)

This PR also buffs up the security armoury very slightly, adding 2 more
L42As and a box of 16 L42A magazines for FORECON to use if they can
figure out how to actually get inside (Blowing up the fueltanks to the
west of security)

other than that I added some warning stripes to some stuff to make it
look more pretty and messed up some closed walls outside of the maps
bounds that no one can see anyway along with putting a maintjack next to
a locked door for some enviro storytelling

# Explain why it's good for the game

FORECON is meant to gun for the dropship and in my last PR I kinda
messed that up
the optional sec stuff is there to provide a helping hand to FORECON if
they're really in a bad spot
