release: 2.0.0: Panel redesign; new URLs; database from zero

The panel redesign (docs/plans/panel-redesign.md, 27/27). A breaking
release: every panel URL changed and the database starts from a single
baseline - a 1.x /data is not upgraded.

Since the last cut also fixed, all found on the test server:
  - the panel can read the mail queue;
  - port 25 answers with DMARC report ingest on, also next to the
    inbound relay;
  - DMARC reports reach the panel (the delivery service never worked
    since 1.7.0);
  - Postfix start-up warnings about the queue directory.

Cut: CHANGELOG [Unreleased] -> [2.0.0]; image pin 2.0.0 in compose,
README, guide; roadmap, plan and version table.

On the test server, on 252e5d1: go vet ./... ok, go test ./... ok
(22 packages), make e2e ok.

Full detail: CHANGELOG.md (2.0.0).

+- **DMARC reports reach the panel.** A report accepted on port 25 stayed in
+  the queue: the generated delivery service was a bare `pipe` ("fatal:
+  missing user= command-line attribute"), because the generator addressed it
+  under a type Postfix does not have and set `flags=`, `user=` and `argv=`
+  as `-o` parameters, which they are not. Behind that, the command would
+  have refused to run (Postfix starts it without the container's
+  environment) and was never told the recipient, so the check that a report
+  came to the address of its own domain was skipped. The service line
+  carries its arguments, the recipient is one of them, and
+  `export_environment` names what the command reads. No report had been
+  delivered since the feature shipped in 1.7.0; the e2e check asks Postfix
+  how it reads the service.
+- Postfix no longer logs "warning: not owned by root" for the queue
+  directory and its `pid/` at every start: the entrypoint hands the two back
+  to root after its recursive change of owner.
