5.1 SRD Update: 4th Level Spells

[Zanderaf]

Ah damn, another one.

Same as the previous PRs, would appreciate some reviews on this. If everything here is an affront to god, please yell at me.

• Icon updates for spells.
• More Active Effect to track ongoing stuff.
• More Activities for actions that don't consume spell slots.
• More Light Effects for some spells (Fire Shield example below) to follow along their description of emitting light.
• Arcane Eye, Guardian of Faith, and Faithful Hound adapted to work similar to the 2024 ones (summons an actor while still keeping in line with what the spell does.)
