When an upload fails with a transient HTTP error (e.g., S3 rate limiting with HTTP 503), retries would fail with "curl error: Failed to open/read local data from file/application" because the upload source was already exhausted from the previous attempt. Restart the source in init() to ensure it's at the beginning for both first attempts (no-op) and retries (necessary fix). Fixes: #15023 (cherry picked from commit fbd787b)
