Ticket out existing TODOs

[ezra-sg]

Overview

There are 11 TODOs (and an unknown number of commented lines of code / TODO-like comments) in the application right now, some of which seem rather important. These TODOs and comments are effectively lost. They should either be added to the backlog in the form of Issues or removed.

Acceptance criteria

• all TODOs and TODO-like comments should be removed from the codebase and placed in a GitHib Issue

Technical considerations

• search this repo's GitHub issues to see if any describes the same thing as the TODO
  • if not, create a new issue to address the TODO
• replace the TODO in the code with a comment simply linking to the issue, eg.
  // TODO https://github.com/telosnetwork/teloscan/issues/134
