[0.964]Small Update： Adjustment for cards' fusion

This update primarily improves the experience of the Card Fusion system.
Under the new fusion rules, you no longer need to compare card values. Both the effects and values of material cards will be appended to the slots of the base card. This means you have far more chances to craft composite-effect cards with outstanding stats. (For balance purposes, cards with similar values will appear more frequently among the recommended fusion options.)
Other updates:
Fixed a bug where dragging a card to a specific position would erase its target, halting all game progress.
Minor value adjustments for several cards (balance tweaks).
Small UI refinements to create a more cohesive overall art style.
