MechaCat02 05f76514a2 fix(backend): JWT jti, NUL-byte guard, dev-only truncate endpoint
Two bugs surfaced while running the new E2E suite, plus a small test hook:

- jwt.rs: add a per-token `jti: Uuid` claim. Without it, two `create_token`
  calls in the same wall-clock second for the same (sub, role, event_id)
  produced identical JWT bytes — and identical sha256(token) hashes —
  which then collided on `session.token_hash UNIQUE` with a 500. Manifests
  in real use when an admin clicks "Anmelden" twice fast.

- auth/handlers.rs: reject display names containing 0x00. Postgres rejects
  NUL in TEXT columns with `invalid byte sequence for encoding "UTF8"` and
  the request leaks back as a 500. Now returns 400 with a clean message.

- handlers/test_admin.rs + main.rs: new POST /api/v1/admin/__truncate route,
  compiled in always but only **registered** when EVENTSNAP_TEST_MODE=1 is
  set on startup. Truncates every event-scoped table, reseeds config from
  migration defaults, wipes media on disk, and clears the in-memory rate
  limiter. RequireAdmin-gated so it's not anonymous even in test mode. In
  production builds (no env var) the route returns 404 — verified by the
  startup log message.

- services/rate_limiter.rs: add `clear()` so the truncate handler can wipe
  the in-memory window map between tests.

- Dockerfile: bump rust:1.87 → rust:1.88 (current dep tree needs it) and
  COPY ./migrations into the build context so the `sqlx::migrate!()` macro
  can resolve at compile time.

//! Test-only admin routes. **Compiled in always, but only registered when
//! `EVENTSNAP_TEST_MODE=1` is set in the environment.** The route returns a hard
//! 404 in production builds because [`crate::main`] skips registering the handler.
//!
//! These exist to give the Playwright E2E suite a quick "reset everything"
//! escape hatch without forcing tests to maintain raw SQL fixtures or spin up a
//! fresh database container per test.
