[GuideLLM Refactor] core updates for pyproject.toml and settings.py (#352)

## **Summary**

Renames `config.py` to `settings.py` for better semantic clarity
particularly with later config pathways and updates project
dependencies.

## **Details**

- **Module Refactor**:
Renamed `src/guidellm/config.py` to `settings.;py`and updated all import
references across the codebase
- **Dependency Updates**:
- Added new
dependencies: `culsans`, `eval_type_backport`, `faker`, `msgpack`, `pyhumps`, `sanic`, `uvloop`
    - Updated `pytest-asyncio` from `~=0.23.8` to `~=1.1.0`
    - Removed `recommended` optional dependencies section
    - Removed `[dependency-groups]` and `[tool.pdm]` sections
- **Configuration Improvements**:
- Reformatted license specification to use `{text =
"Apache-2.0"}` format
    - Added `target-version = "py39"` to Ruff configuration
    - Improved code formatting and comment alignment in pyproject.toml
    - Enhanced Ruff ignore rules with better documentation
    - Fixed trailing comma in pytest markers
- **Import Organization**: Updated import order in `__init__.py` to
import logger before settings for better dependency flow

## **Test Plan**

- Automated tests are passing

below."

## **Use of AI**

- [ ]  Includes AI-assisted code completion
- [ ]  Includes code generated by an AI application
- [ ] Includes AI-generated tests (NOTE: AI written tests should have a
docstring that includes `## WRITTEN BY AI ##`)
