Balances explosions for stamina combat

[Inadvizable]

What Does This PR Do

• Heavy explosion now stuns for up to 5 seconds depending on bomb armor, and knocks down for triple the duration.
• Light explosion now knocks down for up to 10 seconds depending on bomb armor.
• Frag-12 rounds no longer apply a direct stun on top of the effects of their explosion.

Part of #18179

Why It's Good For The Game

Long stuns feel pretty awful to play with, and we are moving away from them in favor of knockdowns or stamina where appropriate.

Frag-12 rounds are one of the last (maybe the last?) instant stun projectiles available to the crew remaining in the game.

people crawling away slowly from an explosion, missing limbs and trailing blood sounds like an overall improvement to game feel as well.

I do feel that explosion stun/knockdown reduction should be done as a percentage of bomb armor, or at least it should require high amounts of bomb armor like 30+ minimum.

Only needing 10% bomb armor to avoid a knockdown seems odd.

Only needing 10% bomb armor to avoid a knockdown seems odd.

yeah that'd be odd which is why it's not the case, you need 100
