Ability mon Loot Crates

• Added a placeable Loot Crate block that stores its own payment costs and weighted rewards. Breaks drop the block back and spill any configured contents.
• Right-click behavior:
  • Creative/OP users open the admin editor with payment slots (3) and reward slots (9). Edit crate name, animation length (seconds), slowdown, sound/particle toggles, pity settings, per-reward weight/min/max/rarity/allow-NBT, normalize weights, and run a 1000-roll test that reports expected distribution in chat.
  • Other players pay one of the configured item costs (or open for free if none) and trigger a Counter-Strike style opening screen with reel sounds, slowdown, highlight, rarity tag, and optional particles. Rare (Epic/Legendary) wins broadcast to everyone and log server-side.
• Rewards use weighted odds with optional pity timer (guarantees best rarity after threshold misses). Rewards respect allow-NBT toggle; otherwise copies are clean.
• Payments accept any matching stack in the player inventory; failure shows the configured requirement message.
• Networking uses NeoForge payloads so openings and edits sync between client and server.

Using the crate

1. Place the Loot Crate (abilitymon:loot_crate).
2. Admins open it in Creative/OP to load payment and reward items into the slots, tweak settings, then hit Save.
3. Players with the required items right-click to consume payment and watch the spin; the reward is delivered immediately even if the inventory is full (dropped on the ground).

Notes & limits

• Admin checks rely on Creative/OP; explicit permission nodes aren’t wired to an external permission plugin.
• Currency-mod hooks are not implemented; only item payments are supported today.
• Pity counters are stored per-crate and reset on server restart.
• Text fields accept plain values; animation length expects seconds and is clamped to reasonable ranges.
