Views V2 & server-driven filtering

Features Major upgrade for views Views now support loading data for all time, not a max of the last 30 days Views now support specifying a content type: Standard (the default), which shows articles and longform videos Videos Shorts All Views now support a handful of different layouts: List (the default) Grid Large list (large thumbnails + images) Large grid Much better support for shorts Shorts are not included in views by default, but can be opted into for specific views Viewing a list of shorts shows back and forward buttons for easy navigation Server-driven view filtering View filtering has been primarily client-side up until this point, but has been changed to be server-side. This should allow for more predictable performance, and prevent crashes or weird edge cases when working with large item lists. Improvements More intelligent data loading Serial now only loads the minimal amount of data to render the first page, then loads in additional data afterwards. This greatly lowers the time to when Serial is ready to use. Other changes The "Inbox" view is now the "Uncategorized" view to better reflect what content it contains Self-hosted versions of Serial will now not include the welcome page, and instead drop the user straight at the auth screen
