fix: pre-roll/feature pre-roll bumpers not found in library (v1.0.0.8)

TopParentIds-based queries could fail to match Movie items in the
configured pre-roll library even when they appear correctly in the
Jellyfin UI. Look up the library Folder by ID and walk its recursive
children directly instead, matching the path-based approach already
used for the trailer pool.

 changelog:
-  - Add Information-level diagnostic logging to IIntroProvider.GetIntros — logs
-    every call (item, path, and which features are enabled), why an item is

-    troubleshoot why a pre-roll bumper isn't playing
+  - Fix Trailer Pre-Roll / Feature Pre-Roll bumpers not being found — the

+    directly instead of relying on TopParentIds matching, which could fail
+    to match movies even when they appear correctly in the library
