fix: add manual upload-audio workflow, fix grep -c bug (#883)
- new upload-audio.yml: workflow_dispatch with form fields for title,
album, tags, and optional track deletion before upload
- fix grep -c in status-maintenance upload job: grep returns exit code 1
on no match, causing "|| echo 0" to append a second "0" line.
use "|| true" instead so grep's "0" output is preserved as-is
