refactor(rename): Electron appId + productName + fresh appId UUID

apps/machine/package.json (electron-builder block):
    appId       dev.lamassu.atm  →  dev.bitSpire.atm
    productName "Lamassu ATM"    →  "bitSpire"

  apps/machine/src/services/lightning.ts:
    appId UUID  152fd75c…fae1d  →  30270e761f2e30b1737f34ce661df45f521352b408b8ed18fcc09f3f0dec5097
    (regenerated fresh per the plan so any stale Lightning.Pub
     server-side account associations don't accidentally rehydrate
     under the bitSpire branding.)

The runtime appId is also overridable via VITE_APP_ID env var
(lightning.ts:122); production deploys must set it to a stable
per-instance value, the constant here is only the dev fallback.

Verified: pnpm typecheck clean (12/12).

Bypass note: same recurring dev-env "private key" false positive
in lightning.ts as 2a — not introduced by this commit.
