ipfs raw format fallback dag

[Marketen]

Update the way directory listings are fetched and decoded from IPFS in the DappnodeRepository class. The main improvement is to support the new behavior of IPFS gateways (Kubo v0.40+), which no longer support cross-codec conversion from dag-pb to dag-json by default. The implementation now fetches and decodes raw dag-pb blocks client-side (Dappmanager), with a fallback to dag-json for older gateways. Additionally, the required dependency for dag-pb decoding is added.

IPFS Directory Listing Improvements

• The list method in DappnodeRepository now first attempts to fetch the raw dag-pb block using ?format=raw and decodes it client-side with @ipld/dag-pb, making it compatible with Kubo v0.40+ and Trustless Gateways. Falls back to fetching as dag-json for older gateways, ensuring backward compatibility.
• Updated the method documentation to explain the new logic and compatibility with IPFS gateway changes (IPIP-524).

Dependency Updates

• Added @ipld/dag-pb as a new dependency in package.json to enable client-side decoding of raw dag-pb blocks.
• Imported the decode function from @ipld/dag-pb in repository.ts to support the new decoding logic.
