Align everything with a new layout.
* Use "baseline" for some special elements, the "flex-item-icon" is for
the issue list only at the moment and I think it should be general
enough now (but not using "flex-item-leading" anymore in this case).
* Make the labels stretch themselves.
1. There is already `gt-ac`, so no need to introduce `flex-item-center`
2. The `flex-item-baseline` and `.flex-item-icon svg { margin-top: 1px
}` seem to be a tricky patch, they don't resolve the root problem, and
still cause misalignment in some cases.
* The root problem is: the "icon" needs to align with the sibling
"title"
* So, make the "icon" and the "title" both have the same height
3. `flex-text-inline` could only be used if the element is really
"inline", otherwise its `vertical-align` would make the box size change.
In most cases, `flex-text-block` is good enough.

1. In many cases, the `flex-list` has previous and next `gt-hidden`
siblings, so relax the CSS selector to remove all ".segument .flex-list"
paddings.
2. Make the "Add key" button can toggle
3. Move help message into the related segment(panel). Otherwise users
would misread the message, eg: the SSH help seemed for GPG because they
are so near
4. Move modal element into the segment element, otherwise it affects the
layout
Replace #26761
It's better to keep children elements simple, and let parent containers
layout the necessary padding/margin.
The old `not(:last-child)` and `.flex-item + .flex-item` are not easy to
maintain (for example, what if the developer would like to use a "tiny
height" item?)
The old approach also makes some UI look strange because the first item
doesn't have proper padding-top.
In this PR, we just simply use `.flex-item { padding: ... }`:
* Developers could manually set the item height they want easily
* It's easier to make it work with various containers -- with padding
(`ui segment`) and without padding (`div`)
And added more samples/examples.

Fix #26617
1. Separate the "flex-list" examples into a dedicated template, and add some more examples
2. Use `flex-basis` instead of `flex-shrink` for `flex-item-trailing`, to avoid wrapping the texts too aggressively
3. Some `flex-wrap: wrap;` are removed
