fix(update): cancel active uploads before downloading + add download stall-timeout

Browse Source 
Clicking 'install update' while many uploads were running left the update stuck at 'Update wird heruntergeladen...' forever, requiring a manual restart. Two causes, both fixed:

1) The 95 MB installer download competed with the active uploads for the (saturated) main process, CPU, network and connection pool, so it barely progressed. The install handler now calls uploadManager.cancel() first — the app quits and relaunches for the update anyway, and the queue is already persisted (non-terminal jobs restore as 'Bereit'), so freeing the resources is correct and makes the download fast.

2) The download read loop had no timeout, so a stalled stream hung indefinitely with no error. Added a 45 s stall-timeout: if no data arrives, the download aborts with a clear message ('Download haengt — seit 45 s keine Daten ... bitte erneut versuchen') instead of freezing, so the retry button works.
