docs: point at the published privacy policy

The policy is an Astro page in the website repo, not a file here — same
shape as Calendula's, which keeps no copy in its own tree at all. The
docs file says so and links both the published URL and the Astro source,
so nobody edits the wrong one; it stays the text of record only until
that page ships, since it is currently the only copy there is.

The README gains a Privacy section with the same link. It links the
published page only — the website repo is on the self-hosted Gitea and
readers of a public README cannot reach it.

Corrects ece4167's message, which said this file stays the policy's source.

 # Agendula — privacy policy
 
+> **The published policy does not live in this repository.** It is
+> <https://jeanlucmakiola.de/agendula/privacy>, built from
+> `src/pages/agendula/privacy.astro` in the website repo
+> ([source](https://gitea.jeanlucmakiola.de/makiolaj/jeanlucmakiola.de/src/branch/main/src/pages/agendula/privacy.astro) —
+> self-hosted Gitea, same shape as Calendula's page). That URL is what the app's
+> **Settings → Privacy policy** row opens and what the Play Console field must
+> hold.

+> This file is the text of record until that page ships, and then becomes a
+> pointer to it. Edit the Astro page, not this — or they will disagree, and the
+> one users read is the other one.
