Domain redirects: send an address to another, over HTTP and HTTPS

A website resource can now redirect to a full address (301 or 302), optionally keeping the path and query, with no target or login. The Add resource wizard has a Domain redirect choice that opens the HTTPS and HTTP sides together. Deleting a site no longer removes redirects. Uses Reef v0.1.10 and Blacktip v0.1.9. Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Add Sandbar alert channel, tags for resources and sites, use Reef's secretbox

VeillaxandClaude Sonnet 5.5	39659f0144	Domain redirects: send an address to another, over HTTP and HTTPS CI / test (push) Successful in 4m36s Details Release / release (push) Successful in 5m10s Details A website resource can now redirect to a full address (301 or 302), optionally keeping the path and query, with no target or login. The Add resource wizard has a Domain redirect choice that opens the HTTPS and HTTP sides together. Deleting a site no longer removes redirects. Uses Reef v0.1.10 and Blacktip v0.1.9.

Resources and sites can be tagged and filtered by tag; sites can be renamed. The secretbox package now comes from Reef v0.1.9 instead of a private copy.

VeillaxandClaude Sonnet 5.5	f93698f63f	Let websites share a port across addresses, and refuse an HTTPS redirect that would take port 80 from a raw port CI / test (push) Failing after 2m18s Details A website on 0.0.0.0 and websites on named addresses can use the same port. An https resource with the redirect on also uses port 80 at its address, so a raw port there is refused, in either order.
