feat(pilot): ProposalBanner scaffold + Proposed state

New component that will replace the task-lane SuggestedFix card. Docks
above the chat composer with a 320ms slide-up animation. This commit
implements only the Proposed state (Tasks 8 & 9 fill Verifying, Partial,
AI-confirming, Nudge, Collapsed).

/**
* ProposalBanner — chat-composer-anchored banner that carries the lifecycle
* of a suggested fix from Proposed → Verifying → terminal outcome.
*
* Replaces the task-lane SuggestedFix card (Phase 8). The banner renders
* above the chat composer in AssistantChatPage. Parent owns the fix record
* and the outcome mutations; this component renders + dispatches callbacks.
*
* Visual reference: docs/FlowAssist_Migration/mockups/06-slide-up-banner.html
* + 07-verify-states.html.
