fix: add error toasts and failure test for sidebar archive

[ColeMurray]

Summary

Follow-up to #570. Addresses review feedback:

• Error toasts: Replace silent console.error calls in archiveSession() with toast.error() so users see feedback when archiving fails
• Failure-path test: Add test that verifies the session stays in the sidebar when the archive API returns 500
• Clarifying comment: Document the split cache responsibility in handleSessionArchived (SWR cache vs local extraSessions state)
• Type narrowing: Change ArchiveSessionDialog.onConfirm from () => void | Promise<void> to () => void since the dialog never awaits it

Test plan

• npm test -w @open-inspect/web — 192 tests pass (including new failure-path test)
• npm run typecheck -w @open-inspect/web — clean
• npm run lint -w @open-inspect/web — clean

Summary by CodeRabbit

• Improvements
  • Enhanced error notifications when session archiving fails, now displaying user-friendly messages instead of silent failures.

📝 Walkthrough

Walkthrough

This PR modifies archive session functionality by narrowing the onConfirm callback type signature, replacing console error logging with Sonner toast notifications in error handling, and adding a test that verifies sessions remain visible when archive requests fail.

Changes

Cohort / File(s)	Summary
Dialog Type Contract packages/web/src/components/archive-session-dialog.tsx	Narrowed onConfirm callback signature from () => void | Promise<void> to strictly () => void, removing Promise support.
Error Handling & Notifications packages/web/src/lib/archive-session.ts	Replaced console error logging with Sonner toast notifications for failed archive requests; error details no longer captured in catch block.
Session Sidebar packages/web/src/components/session-sidebar.tsx, packages/web/src/components/session-sidebar.test.tsx	Added inline documentation describing cache behavior in handleSessionArchived for first-page vs. paginated sessions; added test validating session remains visible after failed archive attempt (500 response).

Summary

PR Title and number: fix: add error toasts and failure test for sidebar archive (#576)
Author: @ColeMurray
Files changed count, additions/deletions: 4 files changed, +50 / -4

This follow-up cleanly replaces silent archive failures with user-visible toasts, adds coverage for the failure path, and clarifies the sidebar cache split without changing the underlying archive flow. I reviewed the changed files and did not find any blocking correctness, security, performance, or maintainability issues.

Critical Issues

None.

Suggestions

None.

Nitpicks

None.

Positive Feedback

• The failure-path test covers the key regression risk from the original sidebar archive change.
• Narrowing ArchiveSessionDialog.onConfirm matches how the dialog is actually used and keeps the prop surface simpler.
• The cache-responsibility comment in handleSessionArchived makes the SWR versus local-state split much easier to follow.

Questions

None.

Verdict (for GitHub PRs)

Approve: Ready to merge, no blocking issues.

260-301: Consider asserting the error toast as well.

This test covers the “session remains visible” part of the failure path, but it doesn’t verify the new user-facing toast.error(...) behavior. Adding that assertion would cover the regression end-to-end.

The test currently verifies the session stays visible on archive failure but
doesn't assert the user-facing error toast; update the test in
session-sidebar.test.tsx to also mock/spyon the toast.error function (or import
the toast mock used elsewhere) and assert it was called with the expected error
message after the failed POST to "/api/sessions/session-1/archive" (the existing
fetchMock and the interactions around SessionSidebar, MOBILE_LONG_PRESS_MS, and
the "Archive" confirmation button should remain unchanged) so the test verifies
both visibility and that toast.error was invoked.
