Clean up unused commands (#6570)

## Problems
- `AdjustNumberProperty` and `UpdatePropIfExists` command aren't used
- `deleteValuesAtPath` and `applyValuesAtPath` are defined in command
runners, but are actually widely used helpers

## Fix
- Delete `AdjustNumberProperty` and `UpdatePropIfExists`
- Move `deleteValuesAtPath` and `applyValuesAtPath` into a dedicated
utils file

**Manual Tests:**
I hereby swear that:

- [x] I opened a hydrogen project and it loaded
- [x] I could navigate to various routes in Play mode
