Spool page for NFC links, bridge address; vendor-first new spool form

- /s/<id> shows a spool: rest in Spoolman and CC2 Control, where it is,
  last booking, history, links to Spoolman and the tag generator.
- Setting "Adresse der Bridge"; the tag generator can put <address>/s/<id>
  on the tag, so an iPhone held to the roll opens that page.
- New spool: vendor and material chosen from Spoolman, the vendor's
  filaments offered, values taken from similar filaments, duplicates
  pointed out and never created twice.
