fix: use hash-router URL format for listing links in email adapters (#335)

The UI is served through a HashRouter, and most adapters (telegram,
slack, discord, ntfy, ...) already link to ${baseUrl}/#/listings/listing/:id.
The email adapters (resend, smtp, mailJet, sendGrid) and the http adapter
were missing the /# - the router never saw the route and dumped the user
on the default overview instead of the listing.
