Allow click-to-carry pokemon and sell with hotkey while held

[jorgejuniordev]

Summary

• Clicking a board pokemon now picks it up onto the cursor (no need to hold the mouse button while moving).
• Pressing the sell hotkey (default E) sells the currently dragged or click-carried pokemon, not only the hovered one.
• Right-click cancels click-carry and returns the pokemon to its original cell; traditional click-and-drag still works.

Test plan

• Click a bench/board pokemon: it should stick to the cursor and show the sell zone
• Move the cursor and left-click a board cell to place it
• Click a pokemon, then press E: it should sell without dropping on the sell zone
• Click-and-drag a pokemon (hold button), press E mid-drag: it should sell
• Hover a pokemon and press E (existing behavior): it should still sell
• Right-click while click-carrying: pokemon returns to original spot
• Confirm traditional drag-drop onto sell zone still sells

I just tested your code and I still need to hold the mouse button to drag a Pokémon. Have you tested this code or did you just prompt an AI ?
