fix(helpers): ent-4366 optional chaining for numbro

[cdcabrera]

What's included

• fix(helpers): ent-4366 optional chaining for numbro

Notes

• convenience for behind the scenes. there are scenarios where the hook based components will "do all the things" to setup and can cause issues with functions expecting strict types
• we also expanded the RHOSAK decimal conversion check using numbro to confirm that as long as we don't receive a decimal places higher it will trim values. In RHOSAKS case we cap at 5 decimal places for all metrics. Instance hours, in theory, should cap itself at 2.
  • If it doesn't we'll have to go back and create a custom graph mod so that each metric can set its own graph x/y axis ticks if it's standalone. Right now the graph only allows setting the x/y axis ticks as a whole. It should be a similar mod to the x/y graph axis label.

How to test

Coverage and basic unit test check

1. update the NPM packages with $ yarn
2. $ yarn test
3. confirm all tests pass. there should be no visual changes associated with this update.
