[bencegadanyi1-nhs]

Summary

✨ New Feature

Details

Added "go back" link functionality to fix an accessibility audit issue and make navigation more consistent across the Prescription Tracker UI

What’s new:

• NavigationProvider – keeps track of history + search params
• useBackNavigation hook – centralised back nav logic
• EpsBackLink component – reusable, accessible back link
• Smart routing:
  a. behaves like normal browser back in standard flows
  b. preserves search context (e.g. list → results → patient search)
  c. treats search list tabs as a single page (avoids polluting history)
  d. context-aware: if navigating from a future-dated list → details, “Back” takes you to the same list, not current prescriptions

Other improvements:

• Keeps original search params when going back
• Better breadcrumb behaviour across entry points (basic details, NHS number, prescription ID)
• WCAG fix: back link now sits outside <main>
• changes "Go Back" strings to "Back"
