The padding-top of the orange notification set in
ext.echo.styles.alert.less was being overriden by the `padding-top: 0`
set in UserLinks.less which was intended to only override the padding
set in Menu.less.
This commit:
* Scopes the li styles in Menu.less to apply only to the legacy user
menu (found in both legacy and modern vector with the consolidated user
links feature off) which appears to be the only menus that needs these
rules.
* The padding-top previously in UserLinks is no longer needed as a
result of the above point.
* Adjusts/cleans up the positioning of the orange notification by
removing an unneeded margin/padding-top and setting the top to 100% (the
previous `calc` statement was unintentionally resulting in 112%).

Reduces the min-width to 340px with several changes at lower
resolutions
* collapses create account into dropdown
* hides language button and user messages
* The search component is updated to include a search toggle which
can be used to hide and show the search input at lower resolutions
- this leads to a slight HTML change with caching implications,
it also moves away from a BEM usage which is not standard for this
repository.
* limits width of logo based on the dimensions we display
in mobile
