Offload one more MoE expert to CPU on frank-default-small (34→35 of 40)

- N_CPU_MOE 34→35: 5 expert layers on GPU instead of 6. Frees ~0.4-0.8 GiB
  VRAM for OOM safety after high-load sessions OOM'd at 32 and 33.
- Sync stale doc references (deployment.md, Dankserver System Specs.md)
  that still claimed 32/8; specs now estimate ~1.8 GiB headroom at 35.
