feat: SOTA image enhancement with one-click auto-improve (#55)

Browse Source 
* feat(image-enhancement): add analysis and correction types

* feat(image-enhancement): implement auto-enhance analysis and correction engine

* test(image-enhancement): add unit tests for auto-enhance engine

* feat(image-enhancement): add API route with analyze endpoint and register in constants/i18n

* feat(image-enhancement): add UI component with mode selector, intensity slider, and analysis badges

* test(image-enhancement): add integration and e2e tests

* fix(image-enhancement): use modulate instead of gamma for exposure correction

Sharp's gamma() only accepts values between 1.0 and 3.0, but brightening
underexposed images computed gamma < 1.0. Switch to modulate({ brightness })
which handles both brightening and darkening correctly.
