Subject: [PATCH] Rename project from Polaroid to Rewind

Drop the Polaroid trademark across the whole project to avoid infringement.
The app is now Rewind, the wordmark reads "Rewind." (keeping the accent
dot), and the frames are called Rewind Cards in user-facing copy.

Renames the package to @rewind/web, the internal identifiers and component
(polaroidsPerRow -> cardsPerRow, POLAROID -> CARD, SheetPolaroid/sheet-card),
the IndexedDB name, and the exported PDF/project filenames. Updates the
manifest, page title, README, and the ADR. Points the Cloudflare worker and
custom domain at rewind.opencore.in.
