duckdns update (silently) fails for tokens with spaces

[0xDEAD]

Describe the issue you are experiencing

If you accidentally have a leading or trailing space in the token for duckdns, the update fails without a warning text. I propose we add a match-validator similar to the one for the domains. Does anybody know if duckdns tokens have a specific format other than [a-f0-9-]+, e.g. a fixed number of characters?
