New error notices in admin settings panel

[benbowler]

Feature Description

Implement these notice variants PUE Errors - UX copy in the Admin Settings panel for admins only

---

Do not alter or remove anything below. The following sections will be managed by moderators only.

Acceptance criteria

• Admin Settings > Email Reports section shows admin-only error notices when the latest batch has failed after all retries for a known category (network_error, permissions_revoked, property_deleted, server_error, scheduler_error, sending_error, other_error per the PUE sheet).
• Each category renders the specified settings-panel copy and CTAs from the sheet (lead text, body, links such as "Go to Analytics settings", "Contact your administrator", "Get help"), and categories without CTAs omit them.
• Notices are shown only when the failure state is present for the latest batch; they clear automatically after a successful subsequent batch or when no terminal failure exists.

Implementation Brief

• [ ] Update assets/js/components/settings/SettingsEmailReporting.js and include error notice added in #11860, after the AnalyticsDisconnectedNotice
• [ ] If any styling tweaks are needed add them in assets/sass/components/settings/_googlesitekit-settings-email-reporting.scss

Test Coverage

• No updates needed
