No route/logic changes - pure label cleanup so the legacy default-server
editor and the multi-server management page are no longer confusable.

New servers previously got a bare ConfigFilePath default with no way
to set/edit EndpointAddress, FirewallMark, or Table afterward. Adds
GET/POST /servers/:id/settings (view/save ServerSetting, admin-only
for writes) and a "Settings" button + modal on each server card in
servers.html. CreateServer now seeds FirewallMark/Table with the same
defaults the legacy single-server bootstrap uses, instead of leaving
them blank.
obj.name is free text (unlike id/interface, which are already
regex-validated server-side) and was being template-literal'd
straight into innerHTML - stored-XSS risk if a server name contains
markup. Escape via jQuery .text()/.html() round-trip.
New admin-only page at /servers-settings (templates/servers.html) lists
servers and creates new ones via POST /servers (ID/name/interface/
addresses/port, key pair generated server-side). Nav gets a "Servers"
link.
templates/users_settings.html gains a multi-select "Server Access"
field wired to the server_ids support added to create-user/update-user
in the previous commit, so admins can now actually assign non-admin
users to specific servers through the UI.
