Move help links from the global header onto each relevant card

The single header-wide help icon (added last release) pointed at a
per-page doc guess, but a page can have several cards covering different
topics. Removed it and added a small help icon directly to each card
that has real corresponding doc content, linking straight to that doc:
Proxy List + Add/Edit host modal (hosts.ejs), Add DNS Provider + Dynamic
A Records (dns.ejs), Add New User + User List (users.ejs), Add
Permission + Permissions (permissions.ejs), Add Group (groups.ejs).

Bumps to v1.1.11.
