fix: session-based counters and hoster cancel context menu

- Done/Error counters now use sessionFilesData (survives removeFromQueueOnDone)
- Uploaded/Total bytes tracked via session accumulators (never decrease)
- Errors no longer shown in Files list (stay in queue for retry)
- Right-click context menu: "hoster abbrechen" cancels all jobs for a hoster
