Enhance JSON metadata generation in ERC20FixedDenomination and update trait labels in EthscriptionsRendererLib

- Improved JSON metadata construction by escaping special characters in token name and symbol.
- Added new trait for "Content URI SHA" in EthscriptionsRendererLib to provide additional metadata.
- Updated trait labels for clarity, changing "Protocol" to "Protocol Name" and "Operation" to "Protocol Operation".
