Simplify ArrangementConfigurator: replace color pickers with compact
pills, add click-to-add from pool, use watcher-based auto-select for
new/cloned arrangements, remove group_colors from save payload.
Enhance SongsBlock preview: color-coded group headers with tinted
backgrounds, PDF download button inside preview modal, .pro download
link per matched song, show DB ccli_id with fallback to CTS ccli_id.
Fix Modal z-index for nested dialogs. Fix SlideUploader duplicate
upload on watch by adding deep option and upload guard. Expand API
log detail sections by default and increase JSON tree depth. Convert
song download button from emit to direct .pro download link.
