Lite v1 / 04 Export — CSV export and wipe local data

[evanqua]

Summary

Add Lite end-of-event data handling: export dispatch logs to CSV and provide clear wipe-local-data controls, without requiring a summary/recap page.

Motivation

Lite mode needs a practical endpoint: keep data local during operations, then export and clear when desired. This satisfies privacy-first workflows without backend storage.

Proposed solution

• Add CSV export action in Lite dispatch/end-event flow.
• Reuse/align with existing log export columns where feasible.
• Add local data wipe controls:
  • Wipe current Lite event
  • Wipe all Lite mode data
• Add clear UX messaging before destructive wipe.
• After wipe, route back to Lite landing/start flow.
• Keep recap/summary page out of Lite v1 scope.

Alternatives considered

• Require summary page for export. Rejected because Lite v1 explicitly avoids recap flow.
• Auto-delete data at end event with no prompt. Rejected due to risk of accidental loss.

Mockups / Examples

• User selects “End Lite Event”
• User exports CSV
• User chooses to wipe current/all local Lite data
• App returns to /lite

Acceptance criteria

• CSV export downloads valid event/dispatch log data for Lite events.
• Wipe actions delete targeted Lite data from browser storage.
• Wiped events cannot be reopened.
• No backend requests are made for Lite export/wipe operations.
• Cloud mode export/summary behavior remains unchanged.

Implementation notes (optional)

• Suggested files, components, or areas to change (helpful for contributors).
• Any API/DB schema considerations.
