fix(zdeploy): report where a domain-less project deployed to

Closes #39.

A project without a public domain finished with no indication of where it went
- the 'Site:' line was gated on $Proj.domain in all four handlers, so an
internal service deployed successfully and said nothing about the result.

The information was never missing, only unused: a domain-less project that
deploys almost certainly has a verify block (the documented pattern for stacks
not published through the edge proxy), carrying the exact port and health path
the deploy had just checked. zdeploy verified against that endpoint and then
discarded it.

New Write-DeployLocation falls back through what the project actually declares:
domain -> public URL; else verify.port (+ path) -> server-local URL flagged as
not publicly routed; else ports.prod -> same without a path; else prints
nothing, as before. Replaces the four call sites, keeping the nextjs handler's
column alignment via -Pad.

Exercised against every shape: domain, verify-only, ports.prod-only, nothing at
all, and padded. CHECKSUMS regenerated; suite 219/219.
