fixes for photo upload form

[ryangroth5]

• What kind of change does this PR introduce? (Bug fix, feature, docs update, ...)

• removes VUE_APP_GRAPHQL_HTTP, not being used. replaced with VUE_APP_API_BASE_URL+"graphql"

• changes photo upload type to GALLERY and post type to PHOTO_UPLOAD to get correct ID

• hides upload if user is not logged in

• refreshes gallery when upload is sent

• uploads the fields collected in the form when it updates the post

• What is the current behavior? (You can also link to an open issue here)

• code indicates that the gallery is updating a POST with the id of the reach being so the wrong post is getting updated and regular users are getting a post not authorized error

• code doesn't update fields from the form

• code uses two ways to indicate the graphql endpoint

• What is the new behavior (if this is a feature change)?

• explained

• Does this PR introduce a breaking change? (What changes might users need to make in their application due to this PR?)

• i don't think so

• Other information: addresses #1797

@drewalth can't request a review from you, here's a first attempt at fixing the form.

sorry for delay on this @ryangroth5 -- I made some small changes and am testing it now. Also made two fixes:

• rapid wasn't displaying properly (because it needs to map through poi_id, check the state rapids, and find rapid name)
• refresh() didn't actually re-load the photos displaying because the state hasn't updated, fixed now
