The fundraising grid's per-contact editor now has a LinkedIn URL field next to name, email, title, and location. It threads through the grid contact object and sanitize (which preserves contact-object fields), and _upsert_contact_from_fundraising now reads and persists linkedin_url on both the update and insert paths — so a LinkedIn entered in the grid lands on the linked contact record. Test: test_grid_contact_link.py extended to assert LinkedIn entered in the grid persists to the contact (idempotent). Frontend html.parser clean.
