feat: add BEXChain assets and metadata (Chain ID 140586)

[bexchainteam]

Adding folder eip155:140586 for BEXChain network.
Included tokens:

• wUSDT
• USDB
• ONE
  Along with their respective .json metadata and .svg logos.

---

Note

Low Risk
Additive static metadata and icons only; incorrect addresses or symbols could mislabel tokens in wallets but does not change application code.

Overview
Adds BEXChain (CAIP-2 eip155:140586) to the token metadata catalog with three ERC-20 entries: USDB, ONE, and wUSDT (display name USDT), each at a fixed contract address with 18 decimals and paired SVG logo paths under icons/eip155:140586/.

The new JSON files follow the same shape as existing chain folders (name, symbol, decimals, erc20, relative logo path); no runtime or registry logic is changed.

USDB logo path mismatch

Medium Severity

The logo field points at a checksummed SVG filename under icons/eip155:140586, but the repo only has the same asset icon stored with an all-lowercase address in the filename. On case-sensitive filesystems and typical raw GitHub URLs, that path does not resolve, so USDB’s logo fails to load and the metadata logo existence check in test/caip.js can fail.

Logo path icon case mismatch

Medium Severity

The logo field points at a checksummed SVG filename, but the ONE icon under icons/eip155:140586/ is stored with an all-lowercase address. On case-sensitive filesystems, fs.existsSync and direct path loads fail, so the token metadata resolves without a logo.
