Add monolithic N2 handover test pipeline with B210 and Quectel

Browse Source 
- Add XML pipeline for N2 handover testing
- Add Docker compose for two monolithic gNBs
- Features:
  * Two monolithic gNBs (gNB1, gNB2) with proper CU+DU parameters
  * Gradual attenuation control using RC4DAT attenuator (5s duration)
  * N2 handover sequence: gNB1 → gNB2 → gNB1
  * Proper channel mapping: ch1-2 for gNB1, ch3-4 for gNB2
  * Telnet server configuration for CI commands
  * Handover-specific neighbor configuration
  * Clean test state management with attenuator reset
