style(adminui): btn-groups + prose trim on top-level ops pages

Group related action buttons into btn-group/btn-group-sm on Alerts, Certificates,
ApiKeys and ScriptEdit; promote the RoleGrants Delete from btn-link to
btn-outline-danger. Replace the two inline style="border-color:var(--alert)"
no-ops with the .notice-alert class, and the undefined --surface-2 token in
Scripts with the theme's shipped --zebra-bg.

Delete unconditional documentation prose now covered by docs/ (Redundancy,
Telemetry, AlarmTracking, security, Reservations, AlarmHistorian, ScriptEditor),
keeping state banners and live captions. Correct the LDAP config key on
RoleGrants to Security:Ldap:GroupToRole (LdapOptions.SectionName) and drop the
same wrong key from Account with its deleted block; reword the stale
"Engine emit (F8/F9) is pending" script-log empty state.
