Summary by CodeRabbit

• New Features

  • Bar charts: optional custom Y-axis labels and dynamic Y-axis width for clearer axis text.
  • Auction UI: state-aware countdowns and status badges (Scheduled / Live / Ended) with formatted end dates.
  • Terms acceptance: supports contract-wallet (EIP-1271) signatures and records contract-wallet status on acceptance.

• Performance

  • Chart rendering optimized with memoization for smoother updates.

📝 Walkthrough

Walkthrough

Adds async EIP-1271 contract-wallet signature verification and a new async validator that returns { isValid, isContractWallet } using an ethers provider; EOA ecrecover checks remain. SpiceBazaar TOS flow now requires a provider, stores isContractWallet in localStorage, and hooks short-circuit contract wallets to skip re-verification. Separately, two BarChart components gain memoized Y-axis formatting, dynamic Y-axis width computation, and an optional yTickFormatter prop; auction UI and countdown hooks are refactored to return and consume an AuctionState-driven result.

Title check	❓ Inconclusive	The PR title contains a typo ('aunction' instead of 'auction') and is vague—it uses 'misc' which doesn't meaningfully convey the specific changes (y-axis rendering fixes, multisig signing fix, ended auction display, and chart alignment improvements).	Correct the typo and use a more specific title such as 'Fix y-axis rendering and auction state display in Spice Bazaar' to clearly convey the primary changes.
