Restore CSS rules from the original fomantic dropdown module that were
not carried over during the migration to a custom module. This fixes
image alignment in dropdown items (e.g. assignee filter avatars) and
restores rules for allowAdditions, empty selection state, and the
multi-select sizer span.

Moved fomantic dropdown css to custom module, tested on the dropdown
devtest page, it renders exactly the same as before while using roughly
half the CSS. The clean up was very conservative, likely more can be
done in the future.
Also, this fixes a bug present on main branch where dropdown border has
incorrect color on hover.
