🤖 Impact AI improvements

🎯 Who it's for: Deed admins using Impact AI

• Bulk nonprofit additions to campaigns — share a list of nonprofits with Impact AI and have them added to a campaign without manually linking each one. The assistant handles routing between campaigns and fundraisers end to end.

• Taglines that always fit — the assistant now reads campaign character limits before writing and self-corrects if needed, so taglines are always ready to save.

✨ Why This Matters

When you're building a campaign around a disaster response or giving season push, speed matters. Bulk additions and auto-fitting copy reduce the back-and-forth that slows launches down.
