Show users how to configure lnd with the neutrino backend instead of
bitcoind. This is useful for resource-constrained systems that can't
run a full Bitcoin node, but provides less privacy and security than
a local bitcoind.

Allow configuring the maximum number of inbound and outbound peers
for neutrino. Default is 8, matching lnd's default.

Use simpler naming for the NixOS option. The option defines which
peers to connect to, not the action of adding them.

Use optionals with explicit list syntax for requires, after, and
extraGroups. This makes it clearer that we're conditionally adding
elements to a list.

Upstream lamassu-server doesn't support DATABASE_URL, so peer auth
via Unix socket isn't currently possible. Document the required
upstream changes and module updates for future implementation.

Replace password-based TCP auth with Unix socket peer authentication:
- Remove lamassu-db-password secret (no password needed)
- Remove lamassu-postgres-setup service entirely
- Use DATABASE_URL with Unix socket: postgresql://user@/db?host=/run/postgresql
- Remove POSTGRES_HOST, POSTGRES_PORT, POSTGRES_PASSWORD env vars
This follows the same pattern as btcpayserver and simplifies the module
significantly. Peer auth uses OS-level user authentication via Unix socket.

Replace hardcoded database password with nix-bitcoin secrets pattern:
- Add lamassu-db-password secret (readable by lamassu user and postgres)
- Generate random 20-char password using makePasswordSecret
- Read password at runtime in service wrapper scripts
- Update lamassu-postgres-setup to read password from secrets
- Update helper scripts to read password at runtime
The password is now automatically generated on first deploy and stored
in ${secretsDir}/lamassu-db-password.

connect. Added a TODO to consider auto-populating certificate.extraIPs
from hostname when it's an IP address.

Current state:
- Admin UI runs on port 443 (hardcoded in upstream)
- devMode and nginx options commented out (would conflict with port 443)
- adminPort option removed (not configurable in upstream)
Future implementation documented in docs/lamassu-future-nginx.md:
- Add --ui-port flag to upstream lamassu-server
- Re-enable devMode, adminPort, and nginx options
- Allow nginx as reverse proxy on 443 with admin UI on internal port

so the port was always defaulting to 3000 regardless of config.

Add option to use neutrino instead of bitcoind for fetching blockchain
data. This allows running LND as a lightweight client that connects to
remote Bitcoin full nodes via P2P protocol.
New options:
- services.lnd.backend: choose between "bitcoind" (default) or "neutrino"
- services.lnd.neutrino.addpeers: list of Bitcoin node peers to connect to

bitcoind 29.x is required for joinmarket.
nixos-25.05 is at 29.0, which is a regression from 29.1.
nixos-unstable is at 30.0, which is incompatible.
Adapted from nixpkgs `96ff46705a694219cefa5155ba52203d9d32e65e`, with
minor modifications to make it compatible with nixos 25.05.
6bc5747951 run-tests: fix `tmpDir` being deleted before it's used (Erik Arvstedt)

Tree-SHA512: 7767634bc098faac5cfeb14d1800f24df89a1ea5d56fe894338ae2d2871c3293a8bafc62ee61b5cb7f9f658b02c2a52bc7f82b86f69d20d1dae86cc6bfe004b3
In `buildTests`, `nixInstantiate` is called in a subshell.
When `tmpDir` is unset before the call, the tmpdir is created in the
subshell and gets deleted before subshell exit (via `trap`).
But subsequent code accesses the tmpdir, which has now been deleted,
leading to an error.
This bug has been undetected for a long time because bash 5.2 has a
bug [1] where `trap` is not always executed, causing the tmpdir to never be deleted.
Bash 5.3 (introduced in NixOS 25.05) now works correctly and exposes the bug.
Fix it by creating the tmpdir before the subshell call.
