BigBlueButton 4.0.0-beta.3

This beta brings a significant Layout System revamp (defaulting to the Unified layout, refined camera sorting and pagination, and a new multi-functional mode with dual sidebar panels). Other highlights include a new WASM-based audio processor (BBBA) running on top of the mic stream, user search in the user list, a redesigned lock-settings modal with a 3-state presenter policy, pinned chat messages for moderators, a "Request to Become Presenter" flow for viewers, persistent pinned apps in the gallery, and Ubuntu 24.04 support for BBB 4.0. Below is a list of the pull requests in this iteration, grouped by component.
