FRE-1670: publish /terms and the support address on the Nessa site

nessa.freno.me/terms was a live 404 although AppSettings.termsOfServiceURL
links it from Settings > Legal and the paywall. The document existed only on
an unmerged branch and had no host-dispatch route, so it could not serve on
the subdomain. Carry the Terms of Use page, add the /terms dispatcher, and
publish nessa-support@freno.me on terms, privacy, contact and deletion.

- src/routes/terms.tsx: host-aware dispatch for nessa; other sites 404.
- src/routes/nessa/terms.tsx: the Terms page; its contact section names the
  support address.
- privacy: add the controller clause and the support address.
- contact/deletion: show the support address; deletion also accepts a
  request by email.
- subdomain-dispatch.test.ts: list directories before filtering to .tsx
  files. The old predicate only ever received file names, so it asserted
  over an empty list and missed the missing /terms dispatch.
- support-contact.test.ts: guard that every contact route renders the one
  address the app shows.

App side unchanged: termsOfServiceURL stays https://nessa.freno.me/terms.
