fix: exclude LoRA Manager sidecar .metadata.json from resume scan

get_latest_save_path() uses a broad glob pattern (f"{name}*{post}")
that matches .metadata.json sidecar files written by model managers
like the ComfyUI LoRA Manager. These sidecars have a later ctime
than the matching .safetensors checkpoints, so max() picks them
as the latest save path.

When torch.load() is then called on the .metadata.json file,
it fails with:
  WeightsUnpickler error: Unsupported operand 123
because JSON is not a valid pickle/safetensors format.

Fix: filter out .metadata.json from the candidate paths list,
following the same pattern as the existing false-positive filters.
