iofill: Smart Pantry & Savings

This update makes iofill faster to set up and more reliable every day. Getting started • Picking your stores is cleaner: one card per store, closest first, with duplicate and gas-station entries gone. • The deal check no longer holds you up. Pick stores while it runs, or skip the step and set up your pantry first. • Email verification works from any device or browser, and signups from the app drop you straight back into the app. Receipts • Fixed the freeze some of you hit after scanning a long receipt. • Rescanning after a crash counts as a retry, not a duplicate. • The purchase date is now editable, with a heads-up if it looks off. It drives every expiration estimate. Pantry • Quick Pantry Check is back and smarter. It asks about items that expired, are about to, or were bought a while ago, not just low stock. • Renaming a scanned item teaches iofill that product's name for next time. • Restock suggestions only include things you actually rebuy. Savings • Redesigned Savings screen with a progress ring, 12-month history, and a goal that scales with your spending. Plus faster dashboard loading and a round of smaller fixes.
