Adds a single_file conversion so community HunyuanImage-2.1 GGUF checkpoints load directly. Closely based on convert_hunyuan_video_transformer_to_diffusers (shared DiT lineage), with HunyuanImage deltas: time_in -> time_guidance_embed, single-block hidden size 3584, and the ByT5 glyph encoder byt5_in -> context_embedder_2. Verified: exact key/shape match vs hunyuanvideo-community/HunyuanImage-2.1-Diffusers (1264->1264, 0 missing/unexpected), and a real from_single_file load of the 6.5GB Q2_K.

Adds
from_single_filesupport for two transformers that were missing it:HunyuanImageTransformer2DModel(incl. GGUF) andIdeogram4Transformer2DModel. Each registers the model insingle_file_model.pyand adds a checkpoint converter insingle_file_utils.py.Combined here (was #13933) since both touch the same two files — one review instead of two, and avoids a registry conflict between them.
