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.
A collection movie's overview renders in a popup that does not scroll,
so a long overview overflows with no way to read the rest. The popup now
scrolls.
The popup owns its own ScrollableText, built from the selected collection
movie's overview when it opens and torn down on Esc so a reopened popup
starts at the top. Scrolling mutates only that owned state. The
background renders the Collection record's overview and the movies
table, neither of which carries a scroll offset, so they cannot scroll
along with the popup. The popup also gains the loading and absent
fallbacks the rest of the tree already has.
Give the collection movie fixture an overview distinct from its
collection's, and a multi-paragraph one, so the snapshots can tell the
two records apart and a scrolled popup is distinguishable from an
unscrolled one.
