* fix(jellycompat): match MediaSourceId across UUID formats (compact vs dashed)
* fix(jellycompat): honor ImageTypes=Backdrop as a filter on /Items
Wholphin genre cards request /Items?imageTypes=Backdrop&limit=1&sortBy=Random
and assume every returned item has a backdrop. Silo ignored ImageTypes, so a
random pick could lack a backdrop (BackdropImageTags: null), crashing Wholphin.
Push the filter down to the catalog browse SQL
(NULLIF(BTRIM(backdrop_path),'') IS NOT NULL) so random/limited selections only
ever consider backdrop-having items; empty genres correctly return [].
* fix(jellycompat): case-insensitive PlaySessionId + api_key in stream auth
Wholphin's jellyfin-sdk-kotlin builds its own direct-play URL
(/Videos/{id}/stream?static=true&playSessionId=...&mediaSourceId=...) with a
lowercase 'playSessionId', no api_key, and no auth header (ExoPlayer's data
source drops it). PlaybackSessionAuth read 'PlaySessionId'/'PlaySessionID'
case-sensitively, so the fallback never matched -> 401 on every direct-play
stream -> forced (often failing) transcode fallback. Resolve PlaySessionId via
newCaseInsensitiveQuery, and likewise accept case-variant api_key in
ExtractToken.
* fix(jellycompat): support Wholphin season item queries
