Daniel Han-Chen bf5c4ac90b Fix/adjust diffusion review findings for PR #5754
Backend
- Fix FLUX.2 klein family default base_repo: black-forest-labs/FLUX.2-klein
  does not exist on the Hub. Point at the Apache 2.0 4B Base instead so
  the from_pretrained call works out of the box for ungated users.
- Serialise concurrent load_model calls with a dedicated _load_lock so
  two /images/load requests cannot both reach pipeline_cls.from_pretrained
  at the same time (would double-spend VRAM and corrupt _pipe).
- When the caller passes a full diffusers repo (no gguf_filename),
  use repo_id directly instead of silently substituting the family
  default. Closes the load-the-wrong-model regression flagged by review.
- Drop negative_prompt from the pipeline call when the loaded pipeline
  does not accept it (FLUX.2 / FLUX.2 klein). Inspect __call__ via
  inspect.signature so we do not maintain a manual class list.
- Best-effort unload the chat backend (llama-server) before a diffusion
  load so a 24 GB consumer GPU can swap between chat and diffusion
  without manual unload steps.

Frontend
- Replace the four curated entries with the actual filenames published
  on the Hub (lowercase flux-2-klein-Nb-Q4_K_S.gguf and flux2-dev*).
- Add an explicit base_repo per curated entry so the backend never
  falls back to the family default for the curated picker.
- Add the Apache 2.0 FLUX.2 klein base 4B entry so first-time users
  have an ungated, no-token-required default.
- Hide the negative prompt field for FLUX.2 / FLUX.2 klein and show a
  small explanatory note instead.

Tests
- Add 6 new backend tests: base_repo override, full-repo (no GGUF)
  no-substitution, concurrent serialise race, signature-based kwarg
  filter, negative_prompt strip on FLUX.2, negative_prompt preserved
  on supporting pipelines. 33 tests passing.
