Unification polish: LinkedIn in the grid inline contact editor (v0.1.0:54)

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.
