feat: Add scripts for mob dependency management and server setup

- Implemented `findMobDependencies.ts` to identify foreign key constraints referencing the Mob table and log dependent rows.
- Created `fullServerSetup.ts` for idempotent server setup, including economy items, item recipes, game areas, mobs, and optional demo mob attacks.
- Developed `removeInvalidMobsWithDeps.ts` to delete invalid mobs and their dependencies, backing up affected scheduled mob attacks.
- Added unit tests in `testMobUnit.ts` and `mob.test.ts` for mob functionality, including stats computation and instance retrieval.
- Introduced reward modification tests in `testRewardMods.ts` and `rewardMods.unit.ts` to validate drop selection and coin multiplier behavior.
- Enhanced command handling for mob deletion in `mobDelete.ts` and setup examples in `setup.ts`, ensuring proper permissions and feedback.
- Created utility functions in `testHelpers.ts` for deterministic drop selection from mob definitions.
