fix(testcontainers): align versions and stabilize PostGIS setup

Unify Testcontainers dependencies to a consistent version and remove
custom container tweaks that caused instability with Podman.

- align all Testcontainers dependencies to 2.0.5
- remove `HostPortWaitStrategy` (PostgreSQLContainer already defines an appropriate wait strategy)
- remove `withReuse(true)` (may retain state across runs and break reproducibility)
