Initial commit: Flutter app + PHP/MySQL backend on Hostinger

Replaces Firebase with a self-hosted PHP/MySQL API served from
winded.prymsolutions.com. Includes full backend (schema, auth, events,
teams, brackets, suggestions, stats, media, file upload) and updated
Flutter repositories and domain models.
