Subject: [PATCH] Make L3VPN RD/VRF filter dynamic (roadmap E4)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both L3VPN dashboards had a static custom 'rd' variable holding only
the '-' (all) sentinel — you could not actually filter by a VRF.
Convert 'rd' to a query variable that discovers route distinguishers
from l3vpn_rib. Degrades cleanly on the (currently empty) lab table:
the query always returns '-', so behaviour is unchanged until real
L3VPN data exists, then RDs auto-populate. Existing panel SQL
('$rd' = '-' OR rd = '$rd') is untouched.
