feat: allow add account predict flow

[VGR-GIT]

Description

Switches the reward point calculation for predict from a hard coded approach to using the rewards API. It also uses the same approach recently introduced in the swaps flow, to allow add their account if it's not correctly tied to their rewards subscription.

Note

Switch Predict to API-based points estimation with opt-in handling, update UI to show points/add-account, and extend rewards types/tests.

• Predict flow:
  • Update PredictBuyPreview to use usePredictRewards(totalFee) and drive rewards UI; compute shouldShowRewardsRow and pass accountOptedIn, estimatedPoints, loading/error to PredictFeeSummary.
  • PredictFeeSummary props renamed shouldShowRewards → shouldShowRewardsRow; add accountOptedIn, error tooltip; render AddRewardsAccount when not opted in; wire RewardPointsAnimation states.
• Hook: usePredictRewards:
  • New signature accepts totalFeeAmountUsd; selects multichain account by POLYGON_MAINNET_CAIP_CHAIN_ID and formats CAIP-10 without bridge-controller.
  • Checks feature flag and subscription, opt-in status/support; estimates points via RewardsController:estimatePoints using POLYGON_USDC_CAIP_ASSET_ID and parseUnits with 6 decimals.
  • Subscribes to RewardsController:accountLinked; returns {enabled,isLoading,accountOptedIn,shouldShowRewardsRow,estimatedPoints,hasError}.
• Rewards UI:
  • RewardPointsAnimation: make infoOnPress optional; hide info icon unless provided; support hideValue from hook.
• Types/Constants:
  • Extend rewards types with EstimatePredictContextDto, add PREDICT to PointsEventEarnType.
  • Add POLYGON_USDC_CAIP_ASSET_ID constant.
• Tests:
  • Comprehensive updates for new props/flows, loading/error states, subscription/opt-in paths, and animation behavior.

Bug: Zero Fees Break Rewards Logic

The early return condition treats totalFeeAmountUsd of 0 as missing data, causing rewards logic to skip when fees are zero. The check !totalFeeAmountUsd evaluates to true for 0, preventing opted-in users from seeing rewards when total fees are exactly zero. This should check for undefined or null instead of falsy values.
