Clearer alerts and smoother dashboard navigation

The dashboard now gives more accurate next steps and handles several navigation edge cases more smoothly.

• Blogs with a billing issue receive the relevant notice, while unaffected subscriptions are left alone.
• Domain notices distinguish between DNS changes, an HTTPS certificate that is still being issued, a mismatched proxy target, and temporary response errors instead of suggesting the same action for every case.
• Domain checks wait until the initial dashboard work has settled and are reused for a short period, reducing repeated work during navigation.
• The language you select remains active without an extra interface swap after the page loads.
• If a deployment replaces an older dashboard bundle while you are browsing, a failed back navigation can reload the current version automatically.
