TE-14.5: gRIBI Scaling - full scale setup, target T0

Summary

Validate gRIBI current scaling requirements (Target T0).

This test uses the same topology and structure as TE-14.3 (Target T1), but with reduced scale parameters:

Parameter	Target T0 (TE-14.4)	Target T1 (TE-14.3)	Description
`NumRepairNHG`	500	1,000	Number of NextHop Groups in REPAIR_VRF
`NumEncapDefaultNHG`	2,500	4,000	NHGs in default VRF backing encap VRF entries
`NumUniqueEncapNH`	10,000	16,000	Total unique encapsulation NextHops
`NumTransitIPv4`	12,600	200,000	IPv4 prefixes in transit VRF `TE_VRF_111`
`NumRepairIPv4`	12,600	200,000	IPv4 prefixes in `REPAIR_VRF`
`NumEncapVRFs`	5	16	Number of encapsulation VRFs
