Unify information-page basic structure across modes

[BigSimmo]

Summary

• Fix cross-mode search performance findings: prescribing catalogue debounce/abort/fields=index, differentials abort/debounce, universal documents typeahead soft-timeout (750ms), shared (search-app) shell to avoid composer remount, and Answer rate-limit in-memory fallback outside production.
• Fix Bugbot regressions: shared-shell pathname navigation (/services → /dsm) syncs searchMode during render (no stale-mode paint) even when the query string is unchanged; extracted ClinicalDashboard lazy imports to stay under the maintainability budget.

RAG impact: no retrieval behaviour change — typeahead documents domain timeout and shell URL sync only; ranking formulas and full /api/search retrieval path unchanged.

Verification

• npm run verify:pr-local — focused Vitest on touched sources (362) plus api-rate-limit / search-shell / universal / route / site-map suites green; docs:check-index OK
• UI verification not run: full verify:ui not required for this pass; mode-home smoke via npm run ensure returned HTTP 200 for /, /services, /dsm, /documents/search, /therapy-compass, /?mode=prescribing, and /api/answer/stream returned 200 after the rate-limit fallback fix
• Verification not run: eval:retrieval:latency / soak / live OpenAI canary — approval-gated provider work; not needed for timeout-only typeahead change

Risk and rollout

• Risk: medium — shared layout remount change and rate-limit fallback behaviour in non-production; production Answer/upload still fail closed when the durable limiter is unavailable
• Rollback: revert this PR; mode routes return to per-segment GlobalSearchShell layouts and prior timeout/fallback behaviour
• Provider or production effects: None

Clinical Governance Preflight

• Source-backed claims still require linked source verification before clinical use
• No patient-identifiable document workflow was introduced or expanded without explicit governance approval
• Supabase target remains [REDACTED] ([REDACTED])
• Service-role keys and private document access remain server-only
• Demo/synthetic content remains clearly separated from real clinical sources
• Source metadata, review status, and outdated/unknown-source behavior remain conservative
• Deployment classification/TGA SaMD impact was checked when clinical decision-support behavior changed

Notes

• Prescribing list rows keep the full catalogue payload so Safety/Monitoring filters and patient alerts still see section-derived signals; keystroke storms are controlled by debounce + abort. fields=index remains for identity-only consumers (cross-mode links).
• Live hybrid RPC cold tails remain a separate approval-gated follow-up.

Warning

Review limit reached

@BigSimmo, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 58 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
