Sharp Resharpening: Safety PR Split

[MPhonks]

About the pull request

This is a split of #11698 containing the safety-logic and QOL improvements to the P9 Sonic Harpoon Artillery Remote Projectile (SHARP) Rifle. It replaces the different firemode timers (2.5s, 5s, defaults to 2.5s) with a mine-safety toggle ("SAFE" mode). Apart from the change of incendiary mines to be strictly square, nothing balance-wise has been changed and is reserved for future PR(s).

Of the QOL changes are included:

• The ability to rearm previously disarmed mines (1s) as the SHARP specialist with a multitool
• The inability of mines to blow up to small xenomorph (facehuggers, lesser drones)
• The ability to see whether a mine has safety, and how long the mine lasts before being disarmed (specialist only)
• Automatic magazine ejection

Explain why it's good for the game

As it stands right now, the SHARP contains fundamental design flaws. SHARP has been stamped off as a "xenoagent" role in the game which does more harm to the marine force than good. This PR does not aim to handhold the kit into becoming "the new meta", but rather addresses scenarios where the usage of the SHARP would be more helpful to aliens than to the marine force.

With SAFE mode, placing mines directly where marines walk and push becomes a reliable tool of both securing the backline and ensuring that marines do not suffer fatalities to the mines when pushed back. The mines refuse to detonate when anyone with IFF can be hurt by them, at the cost of potentially fizzling out when hitting xenomorphs directly, or missing out on kills from the potentially obtained stun they cause.
