FIX(core): Refine results management and UI for dashboard integration

This commit includes necessary updates to existing modules to support and
integrate with the new multi-page architecture and dashboard.

- `utils/results_manager.py`:
- Enhanced `add_results()` to store raw and resampled spectrum data,
enabling the interactive spectrum viewer on the dashboard.
- Added `get_spectrum_data_for_file()` for efficient data retrieval.
- Implemented a robust `clear_all_results()` callback.
- `static/style.css`:
- Added minor style adjustments to ensure visual consistency
across the new multi-page layout and dashboard components.
