Sabnzbd v4.5.5 "Health check failed: sabnzbd get_queue: failed to parse response: json: cannot unmarshal number into Go struct field SabnzbdQueue.queue.noofslots_total of type string"

[christian-haider]

Describe the bug
I configured Sabnzbd v4.5.5 correctly I think. In the card for Sabnzbd I see above error. The general connection to Sabnzbd seems to work, otherwise i would not see German_Magazine_-__32_38__-__2018-07-01_GEO_Epoche_Panorama.part31.rar Reparatur fehlgeschlagen. Nicht genug Reparatur-Blöcke vorhanden (134 zu wenig)

I just setup Dashbrr and have the same issue. AI instruct to downgrade sabnzbd to 4.3.3, i didnt try yet.

SABnzbd changed noofslots/noofslots_total in the /api?mode=queue response from JSON strings to numbers, and dashbrr's SabnzbdQueue struct still types them as string — hence the unmarshal error on every queue/health poll (the connection itself is fine, which is why you still see queue content elsewhere).

Fix proposed in #113: a FlexString type that accepts either form and marshals back as a string, so the frontend contract is unchanged. Running it in production against SABnzbd 4.x — the error is gone and the tile polls normally.
