refactor: task handlers, emitter, tx signer, et.c.
* fallback to custom ethereum checksum validator -> https://github.com/go-playground/validator/issues/1073
* decouple jetsream emitter to separate package
* refactor task handlers into individual files
* add error handler for echo to capture unexpected errors and log them
* move handler dependencies into single struct container -> custodialContainer
* replace signer to use EIP 1559 signer -> celoutils v1
* Add 1 minutes timeout to all custodial tasks
