[Proposal] Remove Ramda and just use Lodash instead

[sendyhalim]

So this is kind of awkward because I'm the one that introduced Ramda into satpam code back then, after looking back and rethinking about the decision, I believe it was a mistake to use both ramda and lodash at the same time:

• It increases the learning barrier for engineers to contribute
• It increases the library size (if you decide to use it on the frontend)
