Bug/v2/viewer annotations (#5245)

Show uneditable annotations on viewer
show editable annotations layer when in annotation tools (sign, add
image, add text)
Remove draw tool from viewer (this is replaced wholesale in an upcoming
PR so it wasn't worth doing the work to ensure it worked with the new
annotation layer set up_)
refactoring work, mostly renaming variables we can use for all
annotation based tools that had sign specific names.
remove "tools" tooltip
