Foundation setup — logo, address, Stripe, EIN

The Foundation card at the top of /welcome covers the basics every Turtini module inherits — branding, payments, and tax docs. You can complete each task right inside the card, no navigating away.

Tasks:
• Upload your logo — click to expand, choose an image (PNG, JPG, or SVG, under 1.5 MB). It auto-saves and a preview appears next to the button. The logo shows up on invoices, sites, signatures, and emails.
• Add your address — inline textarea. Used on invoices, tax docs, and your public profile.
• Connect Stripe — click "Continue to Stripe" inside the card to launch Stripe's secure onboarding (business info, bank account, ID verification). When you're done, Stripe drops you back at /welcome. One Connect account powers POS, invoices, bookings, and dues — wire it once.
• Add your EIN — inline numeric input that auto-formats to XX-XXXXXXX. Required for 1099s, payroll, and W-9 generation.

How completion is detected:
Each task is checked off live from the underlying org doc. As soon as the value is saved, the row collapses with a green check. No need to mark anything done manually.
