Expand VENDOR_PROJECT_KEYS to include all vendor projects: AA_ADTRAN, AA_ADVA, AA_CASA, AA_CISCO, AACOMMSCOP, AA_COMMSCOP, AA_HARMONI, AA_JUNIPER, AA_VECIMA, AA_VIAVI. Both AACOMMSCOP and AA_COMMSCOP variants are included for safety. Update property tests to exercise the full vendor key list instead of only AA_VECIMA. Update full-reference-manual.md with vendor-specific issue type dropdown documentation.
