fix: Cleans up code with feeding pets and adds batch coin flips random check

[kamronbatman]

Summary

• Removes unnecessary extra loops in increasing loyalty while feeding pets.
• Adds Utility.CoinFlips for batch 50/50 successive calls to RNG
• Removes improper usage of Utility.RandomSample() and instead uses Shuffle()

Tip

DEVELOPER TIP
Use Utility.CoinFlips(amount) or Utility.CoinFlips(amount, max) instead of looping and doing Utility.RandomBool() multiple times. The new method is up to 60x faster.

Note

DEVELOPER NOTE
Utility.RandomSample is for sampling unique indices and has no guard rails against duplicate values
