API hints tweaks - Githubissues

Description

This pull request is a follow-up to #3137 to give the flexibility for inherited plugins (i.e. time selector in lcviz or cube extraction in lcviz/rampviz) to override the plugin key shown in the API hints. It also makes the following small tweaks:

fix the styling on a component in the slice plugin
fix styling for "apply RGB presets" button in plot options
fix options for "align_by" in orientation plugin to be the same options as the API
add quotes around the color string in color picker
