28.1-RC4

Changes compared to: 28.1-RC3

Non user facing:

• Fixes an unreleased bug where the MyYoast integration card claimed Yoast AI works even when the site is offline, which was misleading because an offline site cannot reach Yoast's services. #23443
• Improves save-error surfacing and the notice dismiss button in the bulk editor. #23445
• Fixes an unreleased bug where the bulk editor could show and edit posts and their SEO data that the current user was not allowed to edit. #23448
• Guards unsaved edits and pending AI suggestions when switching content types in the bulk editor, matching the appearance-tab behaviour. #23447
• Fixes a bug where a long unbroken word overflowed into the next column in the bulk editor after saving. #23451
• Keeps pending AI suggestions and manual edits actionable when a filter is selected. #23450
