Extends the Sonarr-only corruption scan into a generic per-arr loop (same
pattern as arr_full_rescan.sh) instead of a second script, since the
scan/strike/remediate logic is identical and only the API shape differs.
Radarr's moviefile list is fetched batched to include secondary/alternate-
edition files, not just each movie's primary file.
Also fixes two bugs found while testing: build_arr_path_map()'s internal
non-local `for key in ...` loop was clobbering the per-arr API key
variable, and arr_api()'s error output (stdout, not stderr) was getting
appended into the batch fetch file on any single failed call, corrupting
jq's parse of the whole batch and silently zeroing out that arr's results.
Full-library scans are slow to reach any one show by chance — this lets a test
target a specific known-corrupt file/show without waiting on scan order.
Healarr does the same job but crashes on a Go concurrency bug (unsynchronized
map access) whenever multiple corruption events land close together — confirmed
via its own crash log, not fixable from our side. Processing one file at a time
here sidesteps the whole bug class instead of trying to work around it.
Delete + explicit EpisodeSearch rather than relying on Sonarr's own background
missing-search cycle, since that skips unmonitored episodes and this shouldn't.
