Subject: [PATCH] feat(tui): add logs and config tabs, wire render loop

Implement the Logs tab with a scrollable list viewer that displays
log entries with level-colored prefixes (SSE stream placeholder).
Add the Config tab with a TOML display area and help bar showing
keyboard shortcuts for opening $EDITOR and refreshing config.
