Smaller Improvements

A few smaller changes across the platform:

• The top cited domains card can show 7, 14, 21, or 28 domains instead of a fixed seven.
• Page Tracker uses the date picker for clicks, crawls, prompts, and responses. The range is capped at 90 days.
• New projects show nine models to pick from, including GPT OSS 120B.
• Removing a sitemap asks for confirmation first.
• People who accept an invite without a name on their account are asked to add one.
