refactor(machine): remove dead Lightning.Pub nprofile UI (post-3d cutover)

The LP backend was deleted on dev, so VITE_LIGHTNING_PUB_PUBKEY /
config.lightningPubPubkey are never set — the "add this ATM's node to your
wallet" nprofile QR (IdleView dev button + overlay, SupportView ShockWallet
card + deep-link) rendered empty, and the LP fields in RuntimeConfig
(lightningPubPubkey/lightningPubApiUrl/extensionApiUrl) were never populated.
Remove them. The concept has no clean LNbits analog (the ATM is a cash↔LN
gateway, not a node customers peer with) — tracked as a fresh feature request
on lnbits. ShockWallet stays listed as a downloadable wallet (plain URL).
