Clean up the outline view (#19)

Browse source 
Clean up the source code and interface of the outline view. In addition, [fix a bug](commit/6e42681b719d7ec97c4225ca321225979bf87b56) that could cause `Assembly::realize` to react to itself under certain circumstances. Those circumstances arose, making the bug noticeable, while this branch was being written.

#### Source code

- Modularize the `Outline` component into smaller components.
- Switch from static iteration to dynamic Sycamore lists. This reduces the amount of re-rendering that happens when an element or constraint changes. It also allows constraint details to stay open or closed during constraint updates, rather than resetting to closed.
- Make `Element::index` private, as discussed [here](pulls/15#issuecomment-1816).

#### Interface

- Make constraints editable, updating the assembly realization on input. Flag constraints where the Lorentz product value doesn't parse.
- Round element vector coordinates to prevent the displayed strings from overlapping.

Note that issue #20 was created by this PR, but it will be addressed shortly.
