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 displayed swap amounts, fees, and price impact are derived for v2 quotes, which can affect quote sorting and user-facing numbers; scope is limited to metadata calculation with broad test updates.

Overview
calcQuoteMetadata now accepts both QuoteResponse v1 and v2. V2 inputs are detected with QuoteResponseSchemaV2, normalized via toQuoteResponseV1, and calculated with the existing v1 helpers so swap/bridge UI metadata stays on the legacy shape.

Sent amount and fees change for v2: calcSentAmount takes an isQuoteV2 flag so v2 srcTokenAmount is treated like intent quotes (total commitment, no extra feeData on top). calcRelayerFee now uses a precomputed sentAmount instead of recomputing it. minDestTokenAmount falls back to destTokenAmount when missing.

Metadata output is tighter: calcPriceImpact returns undefined when fiat/USD deltas are missing; optional fields (cost, adjustedReturn, priceImpact, etc.) are only attached when at least one value is present. sumAmounts in number-formatters can sum additional v2 fee keys (normalizedAmount, minAmountUsd, etc.).

Tests and mocks were updated (selector/calculator specs drive expectations through calcQuoteMetadata / toQuoteMetadataV1, EVM vs Solana trade shapes, renamed getMockBridgeQuotes*V1 helpers).
