feat: Perps max order error messaging

[gambinish]

Description

Hyperliquid contracts have limitations on the amount of margin for each token

Contract specs: https://hyperliquid.gitbook.io/hyperliquid-docs/trading/contract-specifications

Market orders:

$15,000,000 for max leverage >= 25

$5,000,000 for max leverage in [20, 25)

$2,000,000 for max leverage in [10, 20)

otherwise $500,000

Limit orders:

10 * maximum market order value

Changelog

Manual testing steps

Best way to test this is by manually hardcoding available balance in hyperLiquidAdapter to 100000000 and then attempting to submit an order with max leverages that fit the above constraints. Not all perps have max 40x leverage. So you'll need to go through various perps to catch all cases.

Note

Adds leverage-based max order value checks for HyperLiquid orders, with new constants, validation logic, tests, and localized error messaging.

• Perps Validation:
  • Add getMaxOrderValue(maxLeverage, orderType) in utils/hyperLiquidValidation.ts to compute order value caps (limit = 10× market cap).
  • Integrate max order value check in HyperLiquidProvider.validateOrder using getMaxOrderValue and formatPerpsFiat.
• Constants:
  • Introduce HYPERLIQUID_ORDER_LIMITS in constants/perpsConfig.ts (market caps by leverage tier; limit multiplier = 10).
• i18n:
  • Add perps.order.validation.max_order_value string in en.json.
• Tests:
  • Expand hyperLiquidValidation.test.ts with comprehensive cases for getMaxOrderValue across leverage tiers, order types, and edge conditions.
