Summary

Replace the /ai-access sidebar with a sticky dashboard header, and turn Proposals into a summary-only list plus a Visual View detail page, matching the approved mockup.

• Sticky header: logo + “AI Access”, text nav (Overview, Access tokens, MCP OAuth, Proposals) with the existing sidebar icons, and Settings / Audit log as icon buttons. On mobile, a left hamburger opens a drawer with all items (Settings and Audit log after a divider).
• Summary-only proposal list with Pending / Conflict / Resolved / All filters, change-count chips, and an inline deploy-pending warning after the title. Rows open the detail page; Approve and Reject are not in the list.
• Detail page: Visual View canvas (change highlights, related-node pills, Compact / Editor positions, moved-node ghosts), outline “← Proposals” on the left, Reject + Node-RED-style Approve split on the right. The approve type defaults from Settings defaultDeploymentType and both segments are disabled while a conflict is unresolved.
• The link returned after submitting a proposal (reviewUrl) now opens #/proposals/<id>. Legacy #proposal=<id> still opens the same detail page.

Test plan

• yarn type-check, lint, format, tests, and build
• Playwright checks of the list, detail, Approve menu, and mobile drawer on throwaway Node-RED 5 and 4 (port 1890 only)
