[Feature] Add Min/Max Status to Merchants (#2806)

# Notes
- Allows operators to set a minimum and maximum status that an item will show for players.
- Allows operators to have items on a merchant that only a GM can see.
- Some servers may use status for different things, so having a minimum and a maximum will allow for more functionality.
- Default of `min_status` is `0` (Player) and default of `max_status` is `255` (Max).
