Reworks and fixes blood drunk miner megafauna (#96286)

## About The Pull Request Blood-drunk miner has been reworked to change it from a DPS race into a more dynamic fight - Buffed health from 900 to 1300 (45% increase), slightly increased speed (3 -> 2.5), increased saw damage (6/10 -> 8/12) to compensate for other changes below - Slightly reduced PKA shot damage (20 -> 18) - Saw attacks now have a slightly longer delay inbetween hits (especially in unfolded form), ***no longer are guaranteed to hit no matter what*** (was a bug which forced players to eat 50 damage to the face) and slow down the miner during the combo - Singular PKA shot has been replaced with a telegraphed barrage of 3 projectiles, during which the miner cannot move, letting players gain some distance - Dash is no longer a teleport but a proper charge akin to that of lobstrocities with a very short chargeup that deals no damage or knockdown, but allows the miner to travel further - Miner's attacks no longer give the target stun immunity for a brief moment (why?) - Default PKA it drops has been replaced with an infernal version, which comes with a cheaper (30% vs 50% of the default one) in-built rapid repeater (that also has a less punishing miss delay) <img width="169" height="143" alt="Aseprite_UfXRbgVuqB" src="https://github.com/user-attachments/assets/3ac257a4-5443-4c7f-a891-4e69f8188cb4" /> --- Full fight with a single basic pen and 2 legion cores, no PKC trophies: (fumbled a bit midway though, pre-PKA projectile damage nerf) https://github.com/user-attachments/assets/40c8af0d-035c-49da-861b-5e74ca7d7551 ## Why It's Good For The Game Current blood-drunk miner is a hard DPS check with unavoidable damage (both due to the bug and instant dashes/PKA hits) that simply requires you to facetank the damage using heals and kill it first before it kills you. This should make the fight a bit longer, more engaging and fairer than it is right now. ## Changelog 🆑 add: Blood-drunk miner now drops an infernal PKA with an in-built improved rapid repeater modification balance: Blood-drunk miner has been reworked with new attacks and patterns fix: Blood-drunk miner's combos are no longer guaranteed to land even if you move away from it /🆑
