chore: refactor ipfs config and metadata retrieval

[svienot]

Description:

• rename CoreConfig.ipfsGatewayUrlPrefix to CoreConfig.ipfsGatewayURL
• Although the implementation now checks for CoreConfig.ipfsGatewayURL = null, the default value for this parameter remains https://gateway.pinata.cloud/ipfs/ for the time being.
• refactor TokenMetadataAnalyzer such that logic to retrieve assets from attributes values is a bit more modular and shared.
• refactor BlobValue to reuse some of the above.

Checklist

• Documented (Code comments, README, etc.)
• Tested (unit, integration, etc.)
