Given that all links are now modals triggered by JS, the anchor links are
just invalid HTML that have no purpose. This commit refactors the HTML to
eliminate them by adding the Bootstrap-native btn-link class to maintain
styling. Fixes part of #6126.
When user name changes are disabled and the disabled name change info icon
shows, trailing whitespace gets linkified because of the link's
inline-block property. Use Handlebars whitespace omission syntax to
eliminate this behavior.
This icon should only show when the user is not an admin and either the
realm or server settings have disabled name changes. Previously the icon
always showed for admin users.
