Mixmix/fix deserialize

[mixmix]

saw some aggressive deserialization of EVERY thing that was valid base64.
was breaking CLI functions badly

• Resolves NOPE, straight to PR 👹

Proposed Changes

Rather than write a "block list" of keys whose value to not convert from base64 => UInt8Array (which would be brittle) I:

• Changed serialization to use a PREFIX so that it is 100% clear that something came from UInt8Array
• Updated tests

Testing

• Unit tests added/updated
• Integration tests added/updated
• Manual testing performed

Checklist

• I have performed a self-review of my code.
• I have added tests.
• I have commented my code.
• I have included a CHANGELOG.md entry.
• I have updated documentation in github.com:entropyxyz/entropy-docs, where necessary.

The migrations assume they will run for a person who's been running main. I'm not writing a migration to fix a broken dev state soz
