* Run full tendermint node in Explorer backend
* Fetch all frontend data from explorer http api
* Small frontend fixes & improvements (Display txs better from a single block's page, decrypt vote packages correctly)
* Reduce WASM binary size:
  * Use go log package in frontend instead of zap (large)
  * Don't use websockets in frontend
  * Implement frontend mirrors of protobuf types used by database. Decode protobuf objects and marshal with json when sending to frontend. This removes the need to import the large protobuf package to the frontend
