chore: refactor helpers related to transaction operations

[maschad]

• Closes https://github.com/FuelLabs/fuels-ts/issues/2835

Summary

I've put these changes on a separate branch so that https://github.com/FuelLabs/fuels-ts/pull/2782 is not blocked by this, but they are related to that pr and require the fixes suggested in that PR. I decided to do this refactor since I was already addressing a bug fix related to those operations.

Checklist

• [ ] I added — tests to prove my changes
• [ ] I updated — all the necessary docs
• [x] I reviewed — the entire PR myself, using the GitHub UI
• [ ] I described — all breaking changes and the Migration Guide

So this PR is going to be merged into master once #2782 is merged? If that's the case, I'd remove the release note description from the body of the PR because refactoring in and of itself isn't worthy of mention.

In this release, we:

• Refactored some helper functions directly related to transaction summary operations
