fix(workspace-server): default-bind to 127.0.0.1 in dev-mode fail-open
In dev mode (`MOLECULE_ENV=dev|development`, `ADMIN_TOKEN` unset) the
AdminAuth chain fails open by design so canvas at :3000 can call
workspace-server at :8080 without a bearer token. Combined with the
existing wildcard bind on `:8080`, that exposed unauthenticated
`POST /workspaces` to any same-LAN peer (S-8 in the audit RFC v1).

Couple the bind narrowness to the same signal that drives the auth
fail-open: when `middleware.IsDevModeFailOpen()` returns true, default
the listener to `127.0.0.1`. Production (`ADMIN_TOKEN` set) keeps
binding to all interfaces — its auth chain is doing the work. Operators
who need LAN exposure set `BIND_ADDR=<host>` explicitly.

* `cmd/server/main.go` — `resolveBindHost()` precedence: BIND_ADDR
  explicit > IsDevModeFailOpen() loopback > "" (all interfaces).
  Startup log line now includes the resolved bind + dev-mode-fail-open
  state for post-deploy auditing.
* `cmd/server/bind_test.go` — 8 t.Setenv table cases covering
  precedence, explicit overrides, dev/prod env words. Mutation-tested:
  removing the `IsDevModeFailOpen()` branch makes the dev-mode cases
  fail with "" vs "127.0.0.1".
