Finish dm-edworth bootstrap: fix Tailscale install, add system-layout meshcore_capture support

- base: Tailscale's per-codename .nosetup.sh install scripts are gone
  (404); switch to the universal tailscale.com/install.sh, and split
  install/enable (always) from auth (only when a key is given) so a
  node without an authkey still gets Tailscale installed, just not
  authenticated.
- meshcore_capture: the current upstream installer (v2.0.0+, what a
  fresh install now produces) uses a completely different layout than
  dm-baldock/dm-ashwell's older flat ~/.meshcore-packet-capture setup —
  dedicated system user, /opt + /etc/meshcore-packet-capture,
  config.d/*.toml, meshcore-packet-capture.service. Added
  meshcore_capture_layout (system/legacy) so the role targets the right
  paths/service name per host without touching the two working legacy
  nodes. New 99-user.toml.j2 replicates the old MQTT broker coverage
  (letsmesh us/eu, meshrank, ukmesh, meshmapper) in the new config.d
  override format.
- dm-edworth: fill in serial_port now that the MeshCore device is
  connected; confirmed running and publishing to all 5 brokers.
- README: fix broken list formatting, document the installer's
  required manual step and why.

+# This is a genuine first-run interactive installer (asks for service

+# when an install already exists. So: run it manually once per node,
+# answering its ~3 prompts (see README), then ansible's `creates:` guard

+# meshcore_capture_layout distinguishes two generations of this upstream
+# installer:
+#   system (default) — install method 1, current (v2.0.0+) upstream default.
+#     Dedicated meshcore-capture system user, /opt + /etc/meshcore-packet-capture,
+#     config.d/*.toml, service meshcore-packet-capture.service.
+#   legacy — what dm-baldock/dm-ashwell were set up with (older installer):
+#     flat ~/.meshcore-packet-capture, .env.local, service meshcore-capture.service.
+#     Kept only so this role stays a no-op/safe on those two nodes; new nodes
+#     should use "system".
