//! Integration tests over the full HTTP surface.
//!
//! These tests are `#[ignore]`d by default because they require a
//! running Postgres reachable via `DATABASE_URL`. To run them:
//!
//!   docker compose up -d postgres
//!   DATABASE_URL=postgres://picloud:picloud@127.0.0.1:15432/picloud \
//!     cargo test -p picloud --test api -- --include-ignored
//!
//! Each `#[sqlx::test]` test runs against a freshly created database
//! with `manager-core`'s migrations applied; tests are isolated and
//! can run in parallel.
