fix(forms): truncate long pathway step codes in decision context

[BigSimmo]

Summary

• Stops long pathway step codes (for example 6B attachment) overflowing the fixed-width decision-context columns on the form detail page.
• Renders only the short form-code head visually, with the full code exposed via sr-only text and a title tooltip (same pattern as FormCodeBadge).
• Aligns splitFormCode with pathwayItems by splitting on any whitespace (/\s+/), including tabs, so qualifier extraction stays consistent.
• Fresh rebase of fix(forms): stop long pathway step codes overflowing the decision context #742 onto current main.

Verification

• Diff limited to form pathway truncation + splitFormCode whitespace alignment
• npm run test -- tests/form-code-badge.test.ts (1 passed, includes 6B\tattachment)
• UI verification not run: presentational truncation helper; hosted Production UI covers forms journeys
• Hosted CI: Static / Unit / Production UI as required by change scope

Risk and rollout

• Risk: low — presentational truncation of pathway step codes + shared code-split helper whitespace
• Rollback: revert this squash merge
• 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 sjrfecxgysukkwxsowpy (Clinical KB Database)
• 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• Source metadata, review status, and outdated/unknown-source behavior remain conservative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

• Replaces closed fix(forms): stop long pathway step codes overflowing the decision context #742. Screenshot queue siblings were landed via fix: land unique open-PR queue onto current main #808/fix: finish screenshot-PR residuals (Also matches order + error focus) #812.

  

Summary by CodeRabbit

• Bug Fixes
  • Improved pathway step code display in the Before, Parallel, and After sections with consistent truncation, accessibility-friendly full-code exposure, and tooltips when qualifiers are present.
  • Enhanced form code splitting so qualifiers are correctly separated even when spacing includes tabs, newlines, or multiple spaces.
• Tests
  • Added coverage to verify form code splitting across common whitespace formats and qualifier/no-qualifier cases.

📝 Walkthrough

Walkthrough

The form detail page adds whitespace-aware code splitting and accessible truncation for qualified pathway step codes in the Before, Parallel, and After pathway lists.

Changes

Pathway code display

Layer / File(s)	Summary
Pathway step code helper and splitting src/components/forms/form-code-badge.tsx, tests/form-code-badge.test.ts, src/components/forms/form-detail-page.tsx	splitFormCode recognizes any whitespace separator and is tested with spaces, tabs, newlines, trimming, and unqualified codes. PathwayStepCode displays the head while exposing qualified codes through screen-reader text and a tooltip.
Pathway list integration src/components/forms/form-detail-page.tsx	The Before, Parallel, and After pathway lists render codes with PathwayStepCode.

recognize the same whitespace separators as pathwayItems, including tabs and
other \s+ matches, so qualifier extraction and fullCode tooltip rendering remain
consistent. Add a regression test covering a value such as “6B\tattachment” and
