test(radarr): pin table search, filter and selection behaviour

Radarr handler tests never asserted which block the search and filter keys
push, so transposing searching_block and filtering_block in a
TableHandlingConfig went undetected. Add a search key and a filter key test
for each of the three handlers that configure them: library, collections and
history.

No test moved a table or list selection off index 0 either, which made
current_selection() and items[0] indistinguishable. Select a non-zero index
in the tests covering every handler that reads a selected row, enriching
fixtures with a second, distinct entry where only one existed.

Several fixtures also asserted against a default value, so the expected
result was indistinguishable from an unset field. The system details tasks
now use two distinct non-default task names, and the add movie body expects
a non-default monitor and minimum availability.
