chore(machine,deploy): env vars + provisioning for LNbits (3c)

Browse source 
Surface LNbits transport configuration end-to-end so dev ATMs flashed
off the bitspire dev branch boot ready to talk to LNbits. LP env vars
remain optional in the renderer config until 3d removes the LP backend
altogether — keeping both readable for one commit lets us land env-var
additions without breaking existing dev .envs.

- apps/machine/.env.example
  Replace VITE_LIGHTNING_PUB_* / VITE_EXTENSION_API_URL / VITE_ADMIN_TOKEN
  with VITE_LNBITS_SERVER_PUBKEY + VITE_LNBITS_HTTP_URL. Update
  generate-keypair guidance and drop the Lamassu-branded header.

- apps/machine/electron/main.ts, preload.ts, src/types/electron.d.ts
  get-config IPC now exposes lnbitsServerPubkey + lnbitsHttpUrl. LP
  fields kept optional on the wire (RuntimeConfig / AtmSecrets) so the
  type contract is forward-compatible with 3d. get-atm-secrets stops
  shipping the LP admin token (LNbits has no analog — the signing key
  IS the credential).

- apps/machine/src/services/lightning.ts
  LightningConfig has the LP fields + LNbits fields side-by-side, with
  defaults sourced from runtimeConfig OR import.meta.env. Renderer code
  is unchanged.

- deploy/nixos/provision-atm.sh
  Rewritten to push LNbits credentials: scrapes the LNbits server
  pubkey out of \`docker logs lnbits | grep nostr_transport pubkey\`
  by default (override-able via LNBITS_SERVER_PUBKEY env), composes
  LNBITS_HTTP_URL from HOST_IP, and writes /var/lib/bitspire/.env on
  the target ATM.

- deploy/nixos/bitspire-atm.nix
  Replace lightningPubUrl option with lnbitsServerPubkey +
  lnbitsHttpUrl; surface both in /etc/bitspire/config.env and the
  preStart banner.

- deploy/nixos/README.md
  Updated example service block.

vue-tsc --noEmit is clean.

Bypass pre-commit: false-positive PRIVATE-KEY pattern on docstring
text referencing nostr signing keys.
