Fix the lint errors

Most are object keys out of order after the rename (dicle, pezkuwi,
bizinikiwi, teyrchains and zagros sort differently from the names they
replaced); they are sorted, behaviour is unchanged. The rest:

- createClass: header.hash is already the BlockHash type; the
  `as any` cast is removed
- ScProvider: WellKnownChain is a string union in @bizinikiwi/connect,
  so `string | WellKnownChain` was `string`; the spec parameter says so
- ScProvider: the jsonRpcResponses loop is a named async function whose
  rejection (chain removed, client terminated) is caught explicitly
  instead of a floating promise
- the fake chain in the spec no longer needs a non-null assertion
- Extrinsic.hash: redundant non-null assertion removed
- metadata-get.mjs writes the 2026 header
