feat(notifications): extend toasts for notifications

[grantfitzsimmons]

Fixes #8602

This PR adds notification toasts (extending the existing toast system) for newly received notifications instead of expecting the user to notice the bell changing color in the bottom left! Non-error toasts open the notification dialog when clicked, disappear automatically after 10 seconds, and are removed when their corresponding notification is deleted. Existing toasts (used only for errors) do not disappear automatically since that information is too important to lose.

This also fixes some legibility issues with toasts, as previously hovering over a toast would make the text brand green, which was not WCAG compliant.

Testing instructions

• Trigger a new notification and verify a toast appears (you can load new notifications manually by clicking on the Notifications item in the navigation menu, especially useful if you're using webpack in development since it fetches notifications infrequently)
• Click the toast and verify the notification dialog opens.
• Verify the toast disappears after 10 seconds (with a cool animation showing how much time is remaining, thanks codepen!)
• Delete a notification and verify its toast is removed while the other notifications remain.
• Purposely cause a crash (you can go to /specify/command/test-error/) and verify that the toast does not disappear.

Summary by CodeRabbit

• New Features
  • New notifications appear as accessible toast alerts with a progress indicator. They dismiss automatically after 10 seconds, and the timer pauses while a toast is focused.
  • Select a notification toast to open the notifications dialog, or dismiss it directly. Clearing all notifications or deleting one also removes its corresponding toast.
  • Notifications display a type-specific heading when available, with a general heading for unrecognized types.

📝 Walkthrough

Walkthrough

Newly fetched notifications can appear as interactive, non-error toasts with localized headings. Toasts auto-dismiss after 10 seconds. Focus pauses the timer. Activating a toast opens the notifications dialog.

Changes

Notification toast delivery

Layer / File(s)	Summary
Shared notification headings specifyweb/frontend/js_src/lib/components/Notifications/NotificationRenderers.tsx	A shared helper returns the localized heading for known notification types and a generic heading for unknown types. Existing renderers use the helper.
Notification toast behavior specifyweb/frontend/js_src/lib/components/Errors/Toasts.tsx, specifyweb/frontend/js_src/css/main.css	Toast messages now support notifications. Notification toasts use polite announcements, a bell icon, and a progress indicator. They auto-dismiss after 10 seconds, with the timer paused while focused.
Fetch-driven toast integration specifyweb/frontend/js_src/lib/components/Notifications/hooks.tsx, specifyweb/frontend/js_src/lib/components/Notifications/Notifications.tsx, specifyweb/frontend/js_src/lib/components/Notifications/__tests__/Notifications.test.tsx	The fetch hook reports newly seen notifications. The component creates corresponding toasts and removes them when notifications are deleted or cleared. Tests cover headings, expiration, dismissal, dialog activation, and dialog contents.

Priority: ➖ Normal

Change: Feature · Severity of issue fixed: Medium

Merge Risk: 🟡 Moderate · up to 914ae

When several notifications arrive together, screen-reader users may not hear every new heading. Address the batch announcement before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 914ae

The new behavior is primarily browser-side presentation. Notification text does not become executable content, and toast dismissal does not delete server records. No material security regression was established, but server-side identity guarantees and broader notification access controls were not verified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated added reach is the current browser's shared toast list, announcement region, and existing notification dialog. The inspected toast callbacks do not grant additional service, tenant, datastore, or deployment authority.

Trust Boundaries and Controls

• observed — Server-supplied notification types select only own properties of the heading map, with a generic fallback for unknown types. Payload-derived heading text is rendered as React text, and the notification supplies neither executable callbacks nor a navigation destination to the toast.

Resilience and Maintainability Implications

• observed — Toast cleanup clears pending timers and retains remaining duration across pauses. Closing uses a functional update filtered by object identity, notification deletion preserves non-notification toasts, and fetch completion is suppressed after its owning effect is destroyed.

Explanation

The toast animation in main.css supports issue #8602. The same file also reformats the global transition-property list without changing its properties. That formatting-only change has no connection to notification toasts or their accessibility.

90-99: 📐 Maintainability & Code Quality | 🔵 Trivial | 🏗️ Heavy lift

Exercise new-message detection through the real hook.

The mock invokes onNewNotifications directly and sets notification state itself. The test can pass even if useNotificationsFetch stops detecting new message IDs. Add an active integration test that renders the real hook, supplies an initial response, then supplies a response with a new notification, and asserts that the second response creates a toast. The existing fetch test is skipped and does not assert toast creation.
