The Radarr, Sonarr and Lidarr tests for editing all indexer settings expected every numeric field to be 1 and returned every previous field as 2. Because the fields were mutually equal, transposing any two of availability_delay, maximum_size, minimum_age, retention and rss_sync_interval in the CLI parameter builder produced an identical request and no test could tell. Radarr additionally expected both boolean flags to hold the same value, hiding a transposition of those two.
Readarr already used distinct values and was the model followed here.
Verified by transposing minimum_age and retention in all four CLI parameter builders at once: before this change only the two Readarr tests failed, while Radarr, Sonarr and Lidarr stayed green. After it, the same mutation is caught by five tests across the three trees.
