fix(upload): use source file mtime for retries; avoid "null"
- On retry, derive lastModifiedInSeconds from File.lastModified()
(if file exists and mtime > 0), instead of transferEndTimestamp - Pass a nullable value to workers rather than the literal "null" string
- Switch to WorkManager Data API (replacing workDataOf) to handle nulls
- Ensures accurate Last-Modified metadata and more reliable conflict checks during retried uploads
