1. Home page file drop now shows quick-action tool selector
2. Auth disabled by default in dev (Docker still defaults to true)
3. Tool settings wrapped in forms - Enter key triggers processing
Adds Zustand file store, useToolProcessor hook for upload/process/download
flow, and 7 settings components: resize (with social media presets), crop
(with aspect ratio presets), rotate/flip, convert, compress (quality +
target size modes), strip-metadata, and color adjustments (brightness,
contrast, saturation, channels, effects). Updates tool-page to render the
appropriate settings panel based on toolId.
