feat(spp_dci_server_disability): tint navbar and apps sidebar green

So an operator running both the SP and the DR side-by-side during the
SPDCI demo can tell the two OpenSPP UIs apart at a glance — SP keeps
the default OpenSPP blue from spp_base_common, the DR shows Material
green-800 in the top navbar and green-900 in the apps-sidebar hover
and active states. The SCSS overrides ship with the DR-only module, so
no styling bleeds onto SP installs.
