feat(cli): fix issue with content hash handling

[sphamjoli]

Description

Fix contenthash decoding in contentManagement.ts. The decodeContenthashToCid function passed 0x-prefixed hex directly to @ensdomains/content-hash which expects raw hex without the prefix. This caused getCodec to misparse the bytes, producing Invalid CID version 112 errors when reading existing on-chain contenthashes. The fix consolidates on the shared cid.ts utilities which already handle 0x stripping correctly.

Testing

How to test:

1. Set a contenthash on a domain: dotns content set <name> <cid>, the current field should now decode correctly on first run instead of showing Unable to decode
2. View an existing contenthash: dotns content view <name>, should display the CID instead of erroring with Invalid CID version 112

Notes

Same root cause as the gateway slice(2) bug. The @ensdomains/content-hash library expects raw hex (e301017012...) but was receiving 0x-prefixed hex (0xe301017012...), causing byte offsets to shift. The cid.ts utility already handled this correctly, contentManagement.ts had a duplicate implementation that didn't.

Nit : please comment on why you are changing code or what the code is doing

Hi Spha - the description and release notes are great - It is more of a nit - I think that often people are reading through code and looking at entry and exit points for functions and code flows - sometimes it can be obvious but often the code is the artefact and the issues and release notes are lost
