Completes the consumer half of bitspire-#70: a paired machine gets its LNbits
transport relay(s) + server pubkey from the pairing, so a blank-.env unit reaches
the backend after scanning a seed — no VITE_RELAY_URL / VITE_LNBITS_SERVER_PUBKEY
provisioning.
- resolveSigner now returns { signer, transport }. transport (relays +
lnbitsServerPubkey) comes from the seed on a fresh pair / seeded resume, and
from the binding on a seedless resume. It's threaded out of resolveSigner
rather than re-parsed in loadLightningConfig because the seed arrives over the
one-shot get-atm-secrets IPC — a second consumer would break that contract.
- bunker_binding persists relays + lnbits_server_pubkey (state.db v11→v12,
nullable so pre-#70 bindings resume and fall back to env). Mirrored into
BunkerBindingRecord (preload + electron.d.ts).
- initializeLightningServices resolves effective transport with env-wins
precedence (explicit env override for dev, else pairing, else a dev-only
localhost relay), mutating CONFIG to a single source of truth and building the
Nostr/LNbits/CLINK clients from the full relay list. Strict + required-config
validation now run on the resolved values.
state.db round-trip test covers the new columns + their absence on a pre-#70
binding. Renderer + electron typechecks and all 38 machine tests pass.
