Replaces the two parallel scripts (fakewallet.sh, regtest.sh) with one
modules/dev-env/scripts/dev.sh — `dev up [--fakewallet|--regtest]`,
plus `down|logs|shell`. Default mode is fakewallet (no docker, no
chains, instant), matching what the prior scaffold did with two scripts
but giving consumers one command and one verb-set to learn.
Drops the now-redundant `lnbits.backend` enum and `features.fakewallet`
option from core.nix. Backend selection is the dev CLI's runtime
concern; a NixOS-level option would be a second knob that can disagree
with the CLI flag at runtime. `lnbits.{host,port}` stay (bind addr,
useful to docs and any later service path). `features.regtest` stays
(gates docker engine installation — consumers who'll never use the
regtest mode shouldn't pay for the container engine).
Strips modules/lnbits.nix entirely. The dev CLI runs lnbits ad-hoc; if
a NixOS-managed lnbits service becomes a real ask later, re-add a
focused module then.

core.nix defines the lnbits-sensei.* options (user, host, features,
backend). lib.nix reserves the config.lnbits-sensei.lib helper namespace
with placeholder stubs. lnbits.nix is a no-op stub that documents the
intended services.lnbits wrap shape and the FakeWallet default.
