Deck Builder Magnified View

Requirements

Add a magnified card view to the DeckBuilderView, similar to the one in DraftView.
Show card details (name, type, oracle text) when hovering over any card in the pool, deck, or land station.
Use a persistent sidebar layout for the magnified view.

State: Added hoveredCard state to track the card being inspected.
Layout:
- Changed the layout to a 3-column flex design:
  1. Zoom Sidebar (hidden xl:flex w-80): Shows the magnified card image and text details. Defaults to a "Hover Card" placeholder.
  2. Card Pool (flex-1): Displays available cards.
  3. Deck & Lands (flex-1): Displays the current deck and land controls.
Interactions:
- Added onMouseEnter={() => setHoveredCard(card)} and onMouseLeave={() => setHoveredCard(null)} handlers to:
  - Cards in the Pool.
  - Cards in the current Deck.
  - Basic Lands in the Land Station.

Verified that hovering over cards updates the sidebar image and text.
Verified that moving mouse away clears the preview (consistent with Draft View).
Layout adjusts responsively (sidebar hidden on smaller screens).
