Force YouTube to show compact grid (max 6 videos per row) rather than "slim" grid (max 3 videos per row) in the new UI they debuted in late 2022 for:

• channel tabs
• home page (also force off "fluid width" such that thumbnail resizing behaves the same as other pages)

Note: subscriptions page should already show a "compact grid" (it's actually a different type of grid that this script doesn't touch).
