feat(server): tone-mapping (#3512)

* added tonemapping

* check for hdr in transcode policy

* merged video thumbnail and transcoding logic

* updated tests

* removed log

* added dashboard option, updated api

* `out_color_matrix` for sdr video thumbs, cleanup

* updated tests & styling

* refactored tonemapping setting

* fixed tests

* formatting

* added tests

* updated api

* set target npl higher for mobius and reinhard

* convert to nv12 before nvenc

* fix test
