Checkout redemption speaks all 29 languages — and the admin stops flickering

A quality day across both sides of the app: what your customers read at checkout, and what you see in the admin.

• Checkout and hub redemption fully localized — every string in the checkout redemption flow and the loyalty hub's redeem dialogs now ships in all 29 languages. A cross-locale audit also fixed translation slips in seven languages, and Polish got a native-speaker-level pass throughout the app.
• No more settings flicker — admin pages now render with your real configuration on the very first paint. Previously some pages briefly showed default values before your settings loaded in; that's gone across every settings page, with a guard test to keep it that way.
• Money fields show your currency — amount inputs in the admin display the actual currency symbol ($, €, Kč) on the side your locale expects, instead of an ISO code.
• Landing page hero colors — the loyalty landing page hero's title and text colors are now customizable, so the section can sit on any brand photo.
