tweak casino mobs and loot

[warriorstar-orion]

What Does This PR Do

This PR makes the following tweaks to the casino ruin:

• It replaces the 14 melee pirate spawns and 2 ranged pirate spawns with a spawn pool of 6 either ranged or melee pirates spread across 17 locations in the casino
• Adds 500 credits to the safe bringing the amount to 1000
• Replaces the two mixed space loot spawners in the safe with two guaranteed rare spawns from that pool
• Adds some windows to the parked shuttles
• Removes some of the gambler corpses

Why It's Good For The Game

The casino is currently a death trap with no good loot. These changes help make it a worthwhile ruin while keeping it a challenge and providing some variety in enemy placement without going overboard. The map tweaks are just tweaks.

Testing

Ensured everything spawned as expected.
