fix(ui): add missing styling for queued/retrying states and processing speed labels

- Add --status-queued and --status-retrying CSS vars to all theme blocks
- Add .download-status-queued/.download-status-retrying CSS classes
- Add .download-progress-fill.queued/.retrying with pulse animation for retrying
- Wire retrying status into hover action buttons and context menu (pause/resume/redownload)
- Show 'Processing…'/'Muxing…' text in speed/ETA columns during processing state
- Fix light theme: add missing --status-* vars to :root block
