fix: restore TUI opt-in defaults and align capped label fixtures

Keep fullscreen env-gated (=== '1'), restore final-label caps to 40/80,
and keep full markCompleted fixture strings while asserting the capped
visible prefixes. Fix session export web_log oversize fixture to exceed
256 KiB in UTF-8 bytes.
