feat(readarr): fetch the shared indexer settings and expose them on the CLI

The fetched settings are only written into app state when nothing is
already held there, so a refresh landing while the user has the settings
prompt open cannot overwrite edits in progress.

The fixtures give every field a distinct value. Settings whose fields
all share one value cannot detect two of them being mapped to each
other's keys.
