Replace the per-model llama-server units with a single service that
uses llama-server's --models-preset (models.ini) and --models-max 2,
so the 35B-A3B and 27B models are loaded on demand from one config.
Drop the now-redundant 27B / 27B-MTP / coder-next variant files and
the unused CacheDirectory + slot-save-path KV-slot handling.
Was set defensively without knowing the actual GPU arch; if ROCm
supports the card natively, the override is at best a no-op and at
worst masks the real arch. Add it back with the right value if the
service actually fails to detect the GPU.

Runs llama.cpp's ROCm build under DynamicUser, with the HF model cache
in StateDirectory (survives systemctl clean) and KV slot saves in
CacheDirectory. Listens on :8000.
