nsecbunkerd#27 enforces token lifecycle at sign time (Option D): an expired
token (`expiresAt`) now stops signing post-bind, not just at connect —
reversing the earlier #24 "TTL is connect-window-only" note. A lapsed TTL
now surfaces as the same BunkerRejectedError as a revoke, so the Phase D
re-pair handling covers both. Docstring corrected to say so.

fund-atm resolves its signer by resuming the bunker binding from state.db
(the connect token is already spent by the main app, so it can't re-pair);
falls back to a dev nsec via VITE_ATM_PRIVATE_KEY. better-sqlite3 marked
external in the esbuild bundle. .env.example + CLAUDE.md document
VITE_SPIRE_SEED as the prod identity, VITE_ATM_PRIVATE_KEY as dev-only.
(fund-atm is slated for deprecation in favour of the operator funding the
wallet directly via the LNbits UI — kept working for now.)

New signer-resolver.ts turns the ATM's pairing state into a Signer:
- seed present, fingerprint differs from stored binding → pair: generate a
transport key, redeem the one-shot connect secret, persist the binding,
reset the bootstrap gate (re-publish hello to the new operator, #56);
- seed matches binding, or binding-only → resume (no re-redeem);
- neither → ephemeral LocalSigner (dev) or throw (strict/prod).
lightning.ts drops the atmPrivateKey plumbing and calls resolveSigner; the
Phase-A Signer seam means nothing downstream changes. App.vue's maintenance
beacon resolves the same way (best-effort, skips if unpaired).

get-atm-secrets now returns { spireSeed, bunkerBinding } instead of the raw
nsec (one-shot semantics kept). Adds IPC handlers + preload bindings for
saveBunkerBinding / clearBunkerBinding / resetBootstrapGate so the renderer
can persist a pairing and re-arm the cassette-state hello on re-pair (#56).
resetBootstrapGate added to state-store. Types mirrored in electron.d.ts.

Swap CLINKClient's MachineIdentity for the Signer abstraction: sign_event /
nip44 now go through the signer (async), so the spire identity can live in a
NIP-46 bunker. The kind-21003 management path (operator-driven manual
dispense, the one live CLINK path on dev) decrypts as the spire via the
bunker; the dormant offer/debit paths are migrated too so they're
bunker-ready when CLINK is re-implemented for the upcoming ndebit/k1 spec
(shocknet/CLINK#7, #8).
