Fix code quality issues in dynamic token implementation

[Copilot]

Addresses code quality feedback from PR #1014: import ordering violations, unused dependencies, type inconsistencies, and non-deterministic token deduplication. This PR has been rebased on the latest staging branch.

Import & Dependency Cleanup

• Moved imports before code declarations in useOnchainTokenBalances.ts (ESM requirement)
• Removed unused imports: useReadContracts, erc20ABI, Abi, EvmToken
• Removed react-window dependency (replaced by @tanstack/react-virtual)

Type Consistency

• Made balanceUsd required in EvmTokenDetailsWithBalance to match OnChainTokenDetailsWithBalance
• Eliminates type casting needed when treating EVM tokens as generic on-chain tokens

Token Deduplication Logic

When multiple tokens share the same symbol on a network, the previous implementation silently overwrote entries. Now uses deterministic prioritization integrated with staging's refactored token management structure:

// Priority: native > higher USD price > lower address (lexicographic)
const shouldReplace =
  (token.isNative && !existingToken.isNative) ||
  (!token.isNative &&
    !existingToken.isNative &&
    (tokenPrice > existingPrice ||
      (tokenPrice === existingPrice &&
        token.erc20AddressSourceChain.toLowerCase() < existingToken.erc20AddressSourceChain.toLowerCase())));

The deduplication logic has been integrated into staging's refactored groupTokensByNetwork function, which now works alongside the new mergeWithStaticConfig and buildPriceLookup functions introduced in the staging branch.

Sort Comparator Fix

Fixed useOnchainTokenBalancesSorted to return 0 for equal elements instead of 1, preventing unstable/incorrect ordering:

// Tie-breaker: sort by symbol alphabetically
return a.assetSymbol.localeCompare(b.assetSymbol);

Logging & Configuration

• Replaced console.log with logger.debug in squidrouter.ts
• Fixed Prettier ignore path and added missing prettier-ignore-end directive

Merge with Staging

This PR includes all changes from the staging branch (96 files changed, 4071 insertions, 779 deletions), including:

• Token management refactoring with separation of concerns
• New animation components and stories
• Phase handler improvements
• Various bug fixes and enhancements

All code quality fixes have been preserved and integrated with the staging branch's refactored codebase.
