A spring collection of improvements across imports, filtering, spam protection, and billing.

🚀 Improvements

Batched imports: Importing thousands of posts no longer times out. Under Board settings → Import and export data → Import data → CSV import, there's a new Batched import toggle that imports posts in batches of 50 in the background, so large migrations finish reliably.
Filter popover: The board's Filter button now opens its own popover instead of sharing the sort menu, keeping the toolbar tidy and making it obvious which filters are active.
Spam protection: Sign-ups, posts, comments, and votes from known disposable and abusive email domains are now blocked automatically across Nolt. There's nothing to configure, and it complements your Banned users and Banned IPs lists under People and privacy.
Date and time picker: A refreshed picker with a cleaner layout, used everywhere you set dates and times in Nolt.
Safer deletion of statuses and Kanban lists: Deleting a status or list on a large board now runs in the background and moves affected posts carefully instead of blocking the UI.
Faster Kanban on big boards: Boards with many posts open noticeably quicker in Kanban view, and assigning people from the board is smoother.
Billing reminders: If a subscription payment fails, you'll now receive clear reminder emails with a link to update your payment details, and we give you time to sort it out before anything is cancelled.

As always, tell us what would make these better.
