[Bug/Feature] Purchase confirmation guard on store checkout — accidental Plutonium spends

[iiamlewis]

Summary

Players can accidentally purchase skins with a single click. There is no confirmation step between clicking an item in the store and the purchase executing — the transaction completes instantly and deducts Plutonium/Caps from the player's balance.

This has generated recurring reports in Discord, increasing in frequency, and at least one manual refund has already been issued. Acknowledged by Evan as a todo.

Steps to reproduce

1. Have a balance of Plutonium/Caps in your account.
2. Open the in-game store.
3. Click a purchasable skin in the store grid.
4. Observe that the purchase completes immediately, with no confirmation.

Expected behavior

Clicking a purchasable item should open a confirmation dialog before any transaction occurs. The purchase should execute only on an explicit Confirm.

Actual behavior

The purchase executes instantly on a single click. Currency is deducted with no chance to cancel, leading to accidental purchases and manual refund requests.

Example report (Discord, 06/11/2026)

Player had Plutonium in account, accidentally clicked a skin, purchase completed instantly with no confirmation.

Acceptance criteria

• Clicking a purchasable item opens a confirmation dialog instead of executing the purchase
• Dialog displays item name, rarity, price, and resulting Plutonium/Caps balance (before/after)
• Purchase only executes on explicit Confirm
• Escape / click-outside / Cancel dismisses the dialog with no transaction
• Cancel is the default focused action
• Server rejects duplicate purchase requests (idempotency key or equivalent) to prevent double-charge on double-click

Scope

• Confirmation dialog on all store purchases (skins, and bundles when shipped)
• Dialog shows item name, rarity, price, and balance before/after
• Idempotent purchase endpoint to prevent double-charge on double-click

The guard should apply to the full checkout path, not just the skin grid — any future purchasable surface (bundles, subscription upsells) should inherit it.
