Replace UU-uploads playlist workaround (proto field 104) with direct requests to the channel Videos tab API (tab="videos"), aligning with Invidious content-type handling. This restores proper continuation tokens and stable pagination (~30 videos per page). Update display logic: - Show channel total upload count as an upper-bound while continuation tokens exist. - On final page, display exact fetched video count. - Ensure page number never falls below current page (fix page reset to "1"). Maintain separate handling: - Shorts and streams tabs continue using tab-specific continuation tokens. Add test: - TestChannelCtokenV5::test_include_shorts_false_adds_filter Fixes issue where channels with many Shorts (e.g., Celine Dept) showed only a few videos and broken pagination under "no shorts" sorting.
