Add Seating Arrangement Settings & Style Update Plan

1. Backend Updates (main.py)

• Update DEFAULT_CONFIG: Add enable_seating (bool, default True), total_tables (int, default 14), and max_per_table (int, default 10).
• Update assign_seat function:
  • Use CONFIG["total_tables"] and CONFIG["max_per_table"] instead of hardcoded values.
  • Check CONFIG["enable_seating"]. If False, return "自由席" immediately.

2. Admin Page Updates (templates/admin.html)

• Style Overhaul: Replace the current light theme CSS with the dark, futuristic theme from index.html to ensure consistency.
• Add Seating Settings Section:
  • Add a checkbox for "开启分桌功能".
  • Add input fields for "总桌数" and "每桌最大人数" (conditionally displayed when seating is enabled).
• Update JS Logic:
  • Load and save the new seating configuration fields.
  • Add toggle logic to show/hide table count inputs based on the checkbox.

3. Frontend Updates (templates/index.html)

• Inject Config: Ensure enable_seating config is accessible in JavaScript.
• Conditional Display:
  • In submitCheckin (new checkin) and searchUser (already signed), check enable_seating.
  • If disabled:
    • Hide seat number displays (#seat-display, #signed-seat-display).
    • Hide tablemate recommendations (#tablemates-container, #signed-tablemates-container).
    • Update text to indicate "自由入座" (Free Seating).
