https://github.com/OpenHands/agent-canvas/pull/721 - this has several new modal fixes to make sure all modals that should have a upper-right close button do. It also contains style cleanup for inner list containers, padding, header size consistency, and small design tweaks for newer modals. A review was done for modal widths and 4 standard widths were created and reused to avoid the many custom widths currently used. @millions-afternoon-47582
