Suppress legend labels

[nmdefries]

Description

Move legend title suppression and plot height to plotly::layout section to make sure the settings are applied correctly.

theme(legend.title = element_blank()) in calls to ggplot should prevent the legend from being labelled, but after converting to a plotly plot using ggplotly, the legend titles reappear and, for the score plot, are doubled. This seems to be related to a package update, although I haven't been able to reproduce the working version. For example, the public dashboard running off of a 2-month old build displays correctly, but a new build off of main exhibits the problem.

Since plotly has a history of incorrectly displaying ggplot settings, just put legend title suppression into plotly settings directly.

Closes #209.

Changes

• server.R: Set plot height and legend.title in plotly::layout.
