* Fix Windows "Non-relative patterns are unsupported" when loading local GGUF models
When a user loads a GGUF model from a local Windows path (e.g.
C:\Users\danie\.lmstudio\models\unsloth\functiongemma-270m-it-GGUF),
the model identifier contains backslashes and a drive letter. Both
load_model_defaults() and _has_specific_yaml() constructed a YAML
filename from the full absolute path and passed it to Path.rglob(),
which rejects non-relative patterns on Windows.
Fixed by detecting Windows-style paths (drive letters, UNC paths,
backslashes) in addition to Unix-style paths, and using only the
directory basename for the YAML filename lookup when the identifier
is a local filesystem path.

* Refactor: reuse is_local_path helper, fix case-sensitive suffix lookup
- Replace inline local-path detection in model_config.py and
inference_config.py with the existing is_local_path() from utils.paths,
which already handles Unix, Windows drive-letter, UNC, and backslash paths
- Fix case-sensitive suffix lookup in load_model_defaults(): the
_REVERSE_MODEL_MAPPING is lowercase-keyed, so suffix comparisons must use
.lower() to match paths like /path/to/Spark-TTS-0.5B/LLM
* Fix WSL path parsing and _has_specific_yaml suffix lookup
- Use normalize_path() before Path() operations so backslash Windows
paths (e.g. C:\Users\...\model) are correctly split on POSIX/WSL hosts
where pathlib treats backslashes as literal characters
- Add suffix-based (2-component and 1-component) lookup to
_has_specific_yaml() so it matches the same resolution rules as
load_model_defaults(), fixing wrong inference params for local
suffix-mapped models like Spark-TTS-0.5B/LLM
