fix(ui): render Output log directly on the console, not as a nested card

The Output tab embedded SessionTerminalView, which is itself a bordered terminal
card with its own header — a card inside the console card. Render the log lines
directly on the console body instead (the console already provides the terminal
chrome, traffic lights, and status chip), with auto-scroll moved to code-behind.
