goose bd1b7c2925 fix(backend): P1 — handler unwrap cleanup + rewrite integration tests
P1 items #6 (JWT expiry) and #7 (refresh/logout routes) were already delivered
in the P0 pass. This commit covers the two remaining P1 items:

#9 — Replace dangerous handler-level .unwrap() calls (13 sites):
* handlers/users.rs: 5x ObjectId::parse_str(&claims.sub).unwrap() in
  get_profile/update_profile/delete_account/get_settings/update_settings now
  return 401 on a malformed subject instead of panicking (matches the guard
  already used in change_password).
* handlers/auth.rs: the login user.id.ok_or_else(..).unwrap() was a latent
  panic bug — the crafted 500 response was discarded. Now returns the clean
  500 via match.
* handlers/health_stats.rs: 6x state.health_stats_repo.as_ref().unwrap() now
  return 503 SERVICE_UNAVAILABLE if the feature is unconfigured, mirroring the
  interactions.rs pattern.
* Left untouched: 14 test/boot-time unwraps and 7 infallible ones (header
  literal parsing, infallible TryFrom). The 3 borderline model-layer
  inserted_id unwraps are flagged for later.

#8 — Rewrite the broken integration tests against a real test DB:
* Split the crate into bin+lib: new src/lib.rs + src/app.rs (build_app), with
  main.rs now a thin entrypoint. Tests build the exact production router
  in-process instead of hitting a live server on a hardcoded port.
* tests/common/mod.rs: helpers that connect to Mongo, build a fresh AppState
  against a unique per-process DB (normogen_test_<uuid>), and tear it down.
  A 1s connectivity probe makes tests skip gracefully when Mongo is absent, so
  'cargo test' stays green without Mongo — CI runs them for real.
* Rewrote tests/auth_tests.rs and tests/medication_tests.rs with the ACTUAL
  API contracts (POST /register {email,username,password}; response has token
  + refresh_token, not access_token; register returns 201). Covers register,
  login (right/wrong password), auth enforcement, refresh rotation + reuse
  detection, logout, and password-change invalidating old tokens.
* Added a 'test' CI job with a mongo:7 service container running
  cargo test --all-targets.
* Synced scripts/test-ci-locally.sh: fixed the stale -D warnings (CI is
  non-strict) and the reverted 'Docker Buildx' claims; added unit + integration
  test steps with a Mongo skip note.

Verified: cargo fmt --check clean, build + clippy --all-targets clean.
Full 'cargo test': 18 unit + 9 auth + 4 medication = 31 passed, 0 failed
(integration tests skip cleanly when MongoDB is unreachable).

//! Auth-flow integration tests.
//!
//! These build the full app in process (via `common::app_for_test`) against an
//! isolated MongoDB test database, so they exercise the real router, middleware,
//! and handlers. They require a live MongoDB; if one isn't reachable the helper
//! returns `None` and every test skips gracefully (see `skip_if_none`).
//!
//! Contracts verified here reflect the *actual* API (post P0):
//! POST /api/auth/register {email, username, password} -> 201 {token, refresh_token, ...}
//! POST /api/auth/login {email, password} -> 200 {token, refresh_token, ...}
//! POST /api/auth/refresh {refresh_token} -> 200 {token, refresh_token}
//! POST /api/auth/logout {refresh_token} -> 204
