🐛 dashboard: remove unlabelled collapsed sparklines

[clubanderson]

Summary

• identify and remove unlabelled collapsed Knowledge sparklines
• remove other bare collapsed-summary sparklines that lacked visible context
• keep labelled/value-backed collapsed trends and expanded dashboard content intact

Validation

• gofmt -l src/pkg/dashboard/dashboard_section_visual_summaries_test.go src/pkg/dashboard/dashboard_section_summaries_test.go
• git diff --check
• node syntax/visual-summary harness for src/pkg/dashboard/static/index.html

Note: per AGENTS.md, local go test/go build were not run; CI is the verdict.

Conclusion: the sparkline removal itself is straightforward, but this PR bundles three undisclosed changes that each collide with another open PR — and one of them is the opposite fix to #10612 for the same failing test. Recommend trimming to the index.html + test changes before a maintainer reviews it further. I have not changed anything.

1. Opposite fix to #10612 — src/pkg/dashboard/openapi_route_parity_test.go (medium).
This adds GET /api/feedback/status to the parity test's exclusion list with the reason "browser-only … not a public data API". #10612 instead documents the route in dashboard/openapi.json. Both make TestOpenAPISpecCoversEveryRegisteredRoute pass; both cannot be the project's answer. The route is registered at pkg/dashboard/api.go:67 and the existing exclusions (openapi_route_parity_test.go:50-60) are all k8s probes — /healthz-class endpoints — so a session-attribution JSON API is a stretch for that list. Not mentioned in the body. A maintainer needs to pick one; I lean toward #10612's.

2. Fifth concurrent regexp rewrite — src/pkg/dashboard/feedback.go, src/pkg/hub/feedback.go (low).
Also not in the body. ^[A-Za-z0-9][A-Za-z0-9-]{0,38}(?:\[bot\])?$ plus the HasSuffix(name, "-") / Contains(name, "--") guards is functionally correct (39-cap, no leading/trailing/double hyphen). But #10612, #10617, #10589 and #10594 each rewrite the same two lines differently; whichever lands first, the other four need rebasing. This hunk should live in exactly one of them.

3. src/docs/api-reference.md refresh duplicates #10608 (and #10594). Not in the body.

4. Direct conflict with #10614 — static/index.html. Both PRs edit the same else if (sectionId === 'knowledge-section' || sectionId === 'audit-section') branch. This PR replaces the audit sparkline with miniText(...); #10614 keeps a ${spark} and builds a richer audit collapsed row around it. These are opposite design decisions on the same element, not a textual nit — if "remove unlabelled sparklines" is the policy, #10614's new audit spark is labelled (aria-label, last-entry, today-count), so it may be fine, but someone should say so explicitly on #10614.

Question for a maintainer: should /api/feedback/status be documented in openapi.json (#10612) or excluded from parity as browser-only (this PR)?
