* Change HealthAnalyzerWindow: split off reusable HealthAnalyzerControl for cryo pod UI
* Improve CryoPodWindow: add health analyzer
* Improve CryoPodWindow: add eject button
This wasn't requested in the issue but I implemented it as practice with the UI system.
* Rewrote GasAnalyzerWindow, split off reusable gas mix viewer for cryo pod
* Change GasAnalyzerWindow: change back to three columns
With two rows you get a layouting bug when there's a lot of different gases, which looks somewhat bad. I didn't feel like fixing the layouting bug (it's an engine issue) so we're going back to three columns. That way you don't ever get two rows in practice.
* Change GasAnalyzerWindow: simplify by disabling Resizable
I added a lot of complexity to make resizable work nicely with a derived max & min size, but it's not necessary.
Since GasAnalyzerControl is no longer used in CryoPodWindow, these changes are no longer relevant to this PR.
* Tidy CryoPodWindow: Remove old workarounds
These are old layouting bug workarounds from the older version of CryoPodWindow that had a ScrollContainer in it. They're no longer necessary. Less ScrollContainers less problems.
* Tidy up: Remove unused imports
* Remove LabelledSplitBar
It was replaced by BeakerBarChart, which is a lot fancier.
* Tidy up: Tiny code style fix
* Change CryoPodSystem: Move code from server to shared
This is still without adding UI prediction
* move a ton of stuff to shared.
* one last thing
* Improve BeakerBarChart: Keep visual entry width when swapping beakers
* Improve BeakerBarChart: Respect beaker order of reagents
* Improve CryoPodWindow: Ensure space for injection buffer
We need to keep space on the chart for the injection buffer after swapping to a full beaker.
* Improve CryoPodWindow: Prettier ejection error
* Improve CryoPodWindow: Add "Cooling patient" status
