Allow longer project names (up to 100 characters)

Project names are currently limited to 50 characters, which cuts off longer event names, especially for projects imported from Check Cherry or HoneyBook. We're raising the limit to 100 characters so you can name events the way your clients describe them, for example "Martinez Lopez Wedding at Hotel del Coronado, Photo Booth + Guestbook". This applies when creating and editing projects in the app, through the AI assistant connection, and during account imports. Long names will display neatly everywhere with the full name on hover.
