feat: show mail import history

docs/development/roadmap.md

@@ -26,6 +26,8 @@ Recently improved:
 - Mail source imports now create sanitized import-history records for manual and scheduled polls.
 - Parsed upload, Gmail, and IMAP reports are now persisted to `dmarc_reports` and `report_records`.
 - Report/domain API reads can hydrate the dashboard projection from persisted data after restart.
+- Mail source import history is visible in the Mail Sources UI.
+- The current Alpine-based UI is allowed by CSP and renders dynamic tables in real browsers.
 
 Implementation note:
 - The legacy `ReportStore` remains as a projection layer for existing report/dashboard code, but durable report data now lives in the database.

 Priority tasks:
 - Expand import attempts with message ID, source, attachment filename, outcome, and sanitized error details.
-- Show import history on mail source detail pages.
 - Report duplicate skips separately from parse failures.
 - Add backfill controls for Gmail and IMAP sources.
 - Improve source rollups so a source IP tracks pass/fail counts over time.

 - Tests now cover a real Google-style ZIP attachment path rather than only mocked parser behavior.
 - Mail source imports now persist sanitized import-history records for manual and scheduled polls.
 - Uploaded, Gmail-imported, and IMAP-imported reports are now persisted to report/record tables and can be reloaded into report/domain views.
+- Mail source import history is now visible from the Mail Sources UI.
+- The current Alpine-based UI can run under the configured CSP, so dynamic tables render in real browsers.
 
 Next tasks:
 - Add per-import result details: skipped duplicates, parse failures, unsupported attachments, and imported report IDs.
-- Add a UI import history view for each mail source.
 - Add mailbox search controls for date range/backfill without requiring code changes.
 - Improve source aggregation so each sender IP keeps pass/fail totals instead of only the latest result.
