Add ammo consumption to weapon firing system

Integrated ammo tracking into the weapon system to consume ammo with each shot fired.

**Modified: src/weaponSystem.ts**
- Added ShipStatus import and private _shipStatus property
- Added setShipStatus() method to connect ship status manager
- Added ammo check in fire() method - prevents firing when ammo <= 0
- Added ammo consumption: consumeAmmo(0.01) after each shot
- Shots are blocked when out of ammo

**Modified: src/ship.ts**
- Connected WeaponSystem to Scoreboard's ShipStatus via setShipStatus()
- Called immediately after weapon initialization (line 111)

This completes the resource management system:
- Linear thrust consumes fuel (0.005 per frame max)
- Angular thrust consumes fuel (0.005 per frame max)
- Weapon firing consumes ammo (0.01 per shot)
- All gauges update automatically via observable events
- Actions are blocked when resources are depleted
