fix: correct user:* scope typo (#26049)

The wildcard entry in `externalLowLevel` was `"user.*"` (period) instead
of `"user:*"` (colon). Every other entry uses the `resource:action`
colon convention, and `parseLowLevelScope` rejects the period form, so
the wildcard was silently dropped from `ExternalScopeNames()` and could
not be requested via `coder tokens create --scope=user:*`.
