Subject: feat(assets): Add new drum samples and improve conversion script

Created a new script, scripts/gen_spectrograms.sh, to robustly convert all audio files in assets/originals to .spec format. The new script is more portable and provides better feedback. Added the newly generated drum and bass samples to the asset list, organizing them by type for clarity. This completes the requested sub-task.
