Screenshots / Proof of Fix

This is a UI-only change. To verify, run the dashboard and visit each page below; a light blue, dismissible info banner should appear at the top linking to the discussion, and the copy makes clear the list is a draft and not final

1. Workflows -> http://localhost:4000/ui/?page=workflows
2. Memory -> http://localhost:4000/ui/?page=memory
3. Prompt Management -> http://localhost:4000/ui/?page=prompts
4. Old Usage -> http://localhost:4000/ui/?page=usage
5. API Reference -> http://localhost:4000/ui/?page=api_ref
6. Playground, then the "Agent Builder (Experimental)" tab -> http://localhost:4000/ui/?page=llm-playground
7. MCP Servers, then the "Network Settings" tab -> http://localhost:4000/ui/?page=mcp-servers

Changes

The draft deprecation list in discussion #32090 proposes retiring several experimental dashboard features on September 1, 2026. This adds a low-key heads-up on each affected page so users find out in-product without it being blatant, and can weigh in before anything is final

A single reusable DeprecationBanner component renders an antd Alert (type="info", showIcon, closable) that names the feature, notes it is on a draft list that is not final, and links to the discussion. It is placed on Workflows, Memory, Prompt Management, the old Usage page, the API Reference tab, the Playground's Agent Builder tab, and the MCP Network Settings tab (which also covers the internal-network-only flag)

Two open questions for reviewers. First, "Learning Resources" is also on the draft list but it is a sidebar link to the external cookbook rather than a dashboard page, so there is nowhere to host a banner; it is left untouched for now. Second, the banner reappears on every visit since dismissal is not persisted; happy to switch to remembered dismissal or a yellow warning style if preferred

Greptile Summary

This PR adds a dismissible informational Alert banner to seven experimental dashboard pages (Workflows, Memory, Prompt Management, old Usage, API Reference, Playground Agent Builder tab, and MCP Network Settings) that appear on a draft deprecation list targeting September 1, 2026.

• A single reusable DeprecationBanner component is introduced with both the discussion URL and target date extracted to named constants, and a clean single named export.
• Each consumer page wraps its existing content in a React Fragment with the banner prepended; the Playground correctly scopes the banner inside the Agent Builder TabPanel so it only appears on that tab.
• No backend or API changes are involved; dismissal state is intentionally session-only (acknowledged in the PR description).

Confidence Score: 5/5

Safe to merge — pure UI addition that prepends a read-only informational banner to experimental pages with no changes to data fetching, API calls, or authentication.

The change is entirely additive: a new stateless display component is added and wrapped around existing page content without modifying any underlying logic. Both previously flagged issues (date not extracted, redundant default export) are addressed in the current version. No backend, auth, or routing code is touched.

No files require special attention.
