Add minimum speed requirement for tackle execution

- Players must be moving at least 2 m/s to execute a tackle
- Add TACKLE_MIN_SPEED constant (2 m/s) in constants.ts
- Add Player.getCurrentSpeed() method to expose current speed
- Check tackler speed in executeTackle() before attempting tackle
- Log speed in tackle debug output for tuning
