feat(readarr): add the add author handler

Handles the add author search input, search results, and the multi-step
add prompt covering root folder, monitor, monitor new items, quality
profile, metadata profile, tags, and confirmation.

Selecting a search result whose foreign author id already exists in the
library routes to the already-in-library popup instead of the add
prompt, so a duplicate add cannot be submitted.
