fix(isn): flip sub-interface naming to real-gear conventions (v0.19.1)

Browse Source 
Owner review of the v0.19.0 demo + Cisco docs/real spine CLI verification:
ACI spines name the VLAN-4 sub-if after the PORT (eth1/49.49, cf.
Eth1/29.29-style in show ip ospf neighbors vrf overlay-1); the ISN Nexus
names its dot1q-4 sub-if after the VLAN (Ethernet1/1.4). v0.19.0 had the
two conventions swapped. 908 tests green.

PR-19: `ospfIf.area`/`ospfAdjEp.area` are now `isn.ospf_area`-driven (default `"0.0.0.0"`) instead of a hardcoded literal.
PR-20: `ospfIf.helloIntvl`/`deadIntvl` are new, driven by `isn.ospf_hello`/`isn.ospf_dead` (defaults 10/40, real ACI defaults) — previously not carried on this MO at all.
PR-22: the ISN-facing `ospfIf`/`ospfAdjEp` on each multi-site spine now sit on a routed VLAN-4 sub-interface (`id`/dn `eth1/{49+si}.4`, was the bare physical port `eth1/{49+si}`) and `ospfIf` gained an `addr` attribute (`172.16.{site.id}.{si+1}/24`) — matching real ACI multi-site spines, which carry the ISN OSPF address on a sub-if rather than the physical port. The underlying physical port's `l1PhysIf`/`ethpmPhysIf` (interfaces.py) are unchanged. Each spine's ISN uplink physical port also gained a simulated `lldpAdjEp`/`cdpAdjEp` (`sysName=ISN-CSW{site.id}`, `portIdV=Ethernet1/{si+1}`, model `N9K-C9364C`) via `build/fabric.py`, the third `add_adjacency` call site — see docs/DESIGN.md's "PR-22" section.
