feat: skip trailers/pre-rolls inaccessible to the current user (v1.0.0.9)

Filters trailer pool items and pre-roll/feature pre-roll bumpers using
BaseItem.IsVisibleStandalone(user), so users without access to the
relevant library are never handed an item they can't actually play —
some Cinema Mode clients hang indefinitely in that case.

 changelog:
-  - Fix Trailer Pre-Roll / Feature Pre-Roll bumpers not being found — the
-    library lookup now walks the configured library folder's children
-    directly instead of relying on TopParentIds matching, which could fail
-    to match movies even when they appear correctly in the library
+  - Skip trailers and pre-roll/feature pre-roll bumpers the current user
+    can't actually access (e.g. a library not in their library access list)
+    — some Cinema Mode clients hang indefinitely trying to play an
+    inaccessible item, so these are now filtered out per-user instead
