Align goal UI with memory activity blocks

Goal status previously used a standalone success-card treatment, which made /goal look visually detached from the transcript. Rework the active goal strip and goal event cards to use the same compact memory/tool-result visual language.

Constraint: Preserve /goal state visibility while reducing alert-like chrome.

Rejected: Continue tuning only goal colors | the layout still read as a separate alert instead of transcript state.

Confidence: high

Scope-risk: narrow
