Practice Mode Rework

The current practice modes need a complete rework as they are too static for real skill development. I suggest upgrading the training ground with interactive bots for these key positions:

Striker: Finishing scenarios with the option to face multiple active defenders at once, plus 1v1 situations against an aggressive goalkeeper.

Defense: Mechanics for intercepting passes, timing tackles against dribbling bots, and clearing aerial balls.

Goalkeeper: Advanced shot-stopping and reaction training tasks with varied angles and shot power.
