fix(server): use srgb pipeline for srgb images (#4101)

* added color-related exif fields

* remove metadata check, conditional pipe colorspace

* check exif metadata for srgb

* added migration

* updated e2e fixture

* uncased srgb check, search substrings

* extracted exif logic into separate function

* handle images with no bit depth or color metadata

* added unit tests
