[ENG-759] P2P Cleanup

[oscartbeaumont]

Changes:

• [x] Rename NodeInformation struct
• [x] Refactor encoding/decoding protocol to reduce bugs
• [x] Split unicast and multicast because using multicast is almost certainly a misuse of the P2P library.
• [x] Remove Volume to Node relation -> Remove node_id from Volume
• [x] Remove Job to Node relation
• [x] Remove Location to Node relation
• [x] Remove duplicate node_local_id from Library struct
• [x] Replace Node table with Instance table
• [x] Remove local_id from Library as it's kinda redundant
• [x] Enable Prisma migrations data loss in prod
• [x] Primitive library-based pairing working
• [x] Fix the migration system yielding an invalid JSON file if original.len() > updated.len()

ENG-759 Refactor P2P crate

Some parts of the P2P system just aren't working how I intended. The change from node level to library level pairing has brought up a heap of technical problems.

• [ ] MDNS needs to be per library per node not just per node
  • [ ] How should the core express the concept of a library to it?
• [ ] All verification of TLS or pairing at a node level needs to be thrown out the window completely
• [ ] Broadcast streams can probably be thrown in the garbage cause they are also certainly the wrong thing to use.
• [ ] Custom PeerId struct should be yeeted and the concept of them shouldn't be exposed to allocation space anymore
• [ ] A connection intent style system probs needs exist as part of the tunnel or similar abstraction
• [ ] Basic binary handling abstraction or utils to clean up and reduce errors in application level code
• [ ] Rename Spacetime module
• [ ] Can or should we unify Tunnel and SpacetimeStream??
