v1.26.2

Fixed

• Adding a watch-only wallet on a pruned node no longer silently fails. It
  used to accept the wallet, show "scanning…", then sit at — forever (a full
  rescan can't run on a pruned node). The dashboard now rejects it up front with
  a clear "a full node is required" message and doesn't add it to the list.
• ./stack backup is more robust and honest: it no longer aborts if it
  can't read the node onion key, warns (instead of silently skipping) when a
  container is down so an incomplete archive isn't mistaken for a complete one,
  and captures the watch-only roster (from 1.26.1).
• ./stack restore with no argument prints a clean usage line instead of a
  raw bash error; ./stack init checks for jq/openssl up front.
• configure.sh validation errors name the offending field instead of
  blaming all three at once.
• Loading page no longer shows an internal Docker IP and points you at
  ./stack doctor if it's stuck; add-form errors are now visually distinct from
  the "scanning" message.
• Documentation consistency pass: corrected the stale "images aren't published"
  note, matched the two doc indexes, and completed the config.json example.

Changed

• CI now measures code coverage (pytest-cov, floor 85%; currently ~93%) and
  cancels superseded runs; new tests pin the inbound-onion entrypoint branch and
  cover previously-dark error paths (wallet RPC, alert channels, version/update
  logic).
