Before this, until the first status for a required context the status
would appear as pending, but would be have oddly (e.g. not clickable).
Update the style of such statuses for clarity:
- use a light background to show them as inactive
- use the `wait` cursor to show their status as oddball (and not clickable)
Setting this styling on the link (or even `li`) doesn't seem to work,
so set it on the `ul`, the actual active links will set the relevant
"active" cursor instead, which seems to work fine.
While at it, extract the status menu to its own template and unify the
disparate bits, mainly in that both the main dashboard and the
per-branch list display the staging instant in UTC on hover: before,
the main dashboard would display a relative delta and provide the
UTC-formatted instant on hover, but the branch would only show a zoned
ISO-8601 instant.
While adjusting is easy, it's unnecessary, we can easily provide the UTC
staging instant there).
Currently the PR becomes successful-green as soon as CI fully passes
but before it's merged, which can be an issue as e.g. merging might be
delayed (there's no visible difference between "CI success" and
"staging merged") or it might ultimately failed (FF error).
Create an intermediate color for "successful" stagings which are still
pending merge.
Also add a fallback message for fast-forward errors instead of en
empty string.
Closes#308
bs4 yields complete vomit on the template as-is (see:
https://imgur.com/a/XIMn7MX).
Add a bunch of color and styling overrides to get something closer to
the original, and move the existing styles to a "proper" scss file
while at it.
