Reworks graphics of tag reading and some api fixes

Reworks the graphics of the NFC-Tag reading process of spool and location tags. Introduces progress bar for reading process. Also first re-work of the spoolman availability (not fixed completly yet). Also fixes an issue where the API request to spoolman and octoprint was sent in parallel. This now happens sequentially to reduce heap load.
