chore: supprime le code mort signale par flutter analyze

Retire imports, champs et variables locales non utilises (14 warnings) :
- imports inutilises (app, database_helper, impact_editor, target_calibration, session_provider)
- champs write-only de capture_screen (_cropService, _scanAnimation, _isCameraInitialized, _alignmentStatus) et _movingShotId
- bloc de calcul mort dans crop_screen et variables locales (themeProvider, ny)

_filterType (history_screen) volontairement conserve : c'est une fonctionnalite de filtre inachevee, pas du code mort.
