Land Advice and Unlimited Deck Building

Requirements

Unlimited Timer: The deck building phase should have an unlimited duration for now.
Land Advice Algorithm:
- Suggest a mana base aiming for a total of 17 lands (including those already picked in the deck).
- Calculate the number of basic lands needed based on the color distribution (mana symbols) of the non-land cards in the deck.
- Provide a UI to view and apply these suggestions.

Timer disabled: useState<string>("Unlimited") is used effectively to remove the countdown mechanism.
Land Suggestion Algorithm:
- Target total lands: 17.
- existingLands calculated from cards in deck with type Land.
- landsNeeded = max(0, 17 - existingLands).
- Scans mana_cost of non-land cards to build a frequency map of colored mana symbols ({W}, {U}, etc.).
- Distributes landsNeeded proportionally to the symbol counts.
- Handles remainders by allocating them to the colors with the highest symbol counts.
- Returns null if no colored symbols or landsNeeded is 0.
UI:
- A panel "Land Advisor (Target: 17)" is added above the Land Station.
- Displays the calculated basic land distribution (e.g., "P: 3, I: 2").
- "Auto-Fill" button applies these counts to the lands state directly.
