ninja stungloves nerf + quirks (tgstation#77810)

## About The Pull Request
the ninja stungloves are no longer a knockdown + shove in one click (not
a stun). clicking on people now first does the shove and THEN knocks
someone down for 3 seconds after a 0.3 second delay. this means you need
to click on them twice
ninja's stealth module now gives you the silent footsteps trait when
active
all ninjas now have the light step and freerunning quirks

## Why It's Good For The Game
ninjas really cool but he doesn't really need 1 click stuns in addition
to all his other tools, he can escape pretty much anything and has a
sword for melee encounters, and knocking someone down instantly is still
really powerful
ninjas getting quirks that fit them is cute i think, makes sense and is
useful

## Changelog
:cl:
balance: ninja's stealth module gives silent footsteps when active
balance: all ninjas now have the light step and freerunning quirks
balance: ninja's hacker module shove no longer stuns in 1 hit. first
shove knocks down and pushes away, second one stuns
fix: fixes ninja shoves not causing sparks
qol: the person in an energy net is now reasonable to hit, the dark part
of the sprite is now an underlay, so you can click the person inside the
net pretty easily and if you wanna hit the net you click the green part
or the darker sides that the human sprite doesnt cover
