fix: give Doctor the host configuration the runtime receives

`pnpm doctor` and `startApi` each read their own subset of the same
environment variables, and the subsets had drifted. Doctor never read
`S3_*` or module secrets at all, so a correctly configured installation
was told its object storage was "not configured" and every module
requiring a bucket or a secret was reported blocked -- while the runtime,
from the identical environment, bound those buckets and ran the modules.

Both executables now map the environment through one
`loadHostConfiguration(env)` in Core, which takes the environment as an
argument and never reads `process.env` itself. Validation stays with the
existing per-domain validators, so each caller keeps its own failure
behaviour: startup refuses a rejected value, Doctor reports it as a
sanitized code.

Doctor's storage option becomes raw input like its mail option, so a
half-configured provider is reported as a blocking configuration failure
instead of throwing before a report exists. The outbound-email check --
computed, counted toward the result, but absent from every rendered
section -- is now printed, and the rendered set is asserted against a
real report so a future check cannot go missing the same way.

+Doctor evaluates the **same host infrastructure configuration the runtime uses**. Both `pnpm doctor`
+and `apps/api` map one deployment environment through the same `loadHostConfiguration(env)` in Core,
+so a configured object-storage provider, a set module secret, and a configured SMTP relay are all
+recognized by Doctor exactly as `startApi` would recognize them — and neither process can silently
+interpret a value differently from the other. Doctor needs no running API process to do this; export
+or set the environment the platform would start with and run the command.
+
+Each optional service is reported in one of three distinct states: **not configured** (absent, and a
+complete deployment), **configured incorrectly** (a blocking failure, reported as a sanitized code
+with no value echoed), or **configured but unreachable** (a warning, because a transient outage is
+not a broken deployment).
