chore: support V1 and V2 quotes when calculating swap metadata

[micaelae]

Explanation

Update calcQuoteMetadata util to handle both V1 and V2 quotes. Legacy metadata calculators continue to use the V1 schema but are able to read V2 quotes

Note

Medium Risk
Changes how sent amounts, relayer fees, and optional metadata are derived for quotes shown in swap/bridge flows; incorrect V2 handling could misstate costs or sorting, though coverage is expanded in calculator and selector tests.

Overview
calcQuoteMetadata now accepts V1 or V2 QuoteResponse values: V2 inputs are detected and coerced through toQuoteResponseV1 before the existing calculators run, so swap/bridge UI metadata keeps using the legacy V1 shape.

V2-specific behavior is layered on top of that path. calcSentAmount takes an isQuoteV2 flag so source fees in feeData are not added on top of srcTokenAmount (same idea as intent-based quotes, avoiding double-count). calcRelayerFee now receives the precomputed sentAmount instead of recomputing it. calcPriceImpact returns undefined when fiat inputs are missing, and optional metadata fields (cost, priceImpact, etc.) are only attached when at least one value is present. sumAmounts in number-formatters can aggregate additional V2 fee fields (normalizedAmount, minAmount, and related fiat keys).

Tests and mocks were updated (factory helpers, selector expectations, EVM vs non-EVM trade shapes) to exercise V2 quotes end-to-end.
