[D11] [UI] Cleaned up various scenes to remove duplicate cameras, event systems, etc. Fixed material error in Roboto Light font material. Added WIP Icon for placeholder elements on the UI. Fixed text anchoring on popups: now defaults to middle center unless specified (this should result in all non pre-defined popups utilising the middle center anchoring instead of upper center). Fixed various popup issues (missing buttons on reporting flow/reset to defaults, etc).
