UI: Refactor all displayed units to use common utils (featuring bigger suffixes)

[DingoEatingFuzz]

Originally I just wanted to make things go THz, PHz, TiB, and PiB. But upon doing so it seemed practical to also make all formatting go through the same code paths. This was a bigger undertaking than anticipated 😄

First, the new stuff before the stuffy details:

A large and quite empty cluster showing aggregate capacity figures reduced to terabytes of memory and terahertz of cpu shares.

Okay, now the stuffy details.

A new utils/units.js file contains all the units logic including:

1. Raw reducers returning the quantity and the unit separately
2. Generic formatters that will reduce values as much as possible, optionally taking a starting unit (since memory is often already in megabytes).
3. Special formatters for "scheduled" figures.

Then there are four helpers that use this file to expose the utils to templates.

I think the first two options listed above make immediate sense: gotta format stuff, gotta have structured output for fancy HTML.

The third option is a style guide proposal of sorts. I think sometimes it makes sense to see numbers in the human format (i.e., reduced as much as possible) and other times it makes sense to see numbers in the scheduler format (i.e., in MiB and MHz regardless of size since that's what job files and such use).

The rule of thumb is to always use the human format unless the number represents one task, allocation, or client, and the number is not realtime utilization.

Before I formally review, I was able to reproduce a failure in the aforementioned flaky test:

I love it!! I appreciate this all being centralised and rationalised. There’s the flaky test and the logging statements but apart from that this looks great. Your style guide-esque proposal makes sense to me.

total success 🥳
