Remove main application file app.py and update dependencies for modular dashboard architecture

- Deleted `app.py`, consolidating the main application logic into a modular structure for improved maintainability.
- Added `dash-mantine-components` dependency to enhance UI component capabilities.
- Updated `pyproject.toml` and `uv.lock` to reflect the new dependency.
- Adjusted imports in `components/__init__.py` and `chart_controls.py` to align with the new modular design.
- Cleaned up unused parameter controls in the market data layout to streamline the user interface.
