- alembic/env.py: strengthen the URL override to fall back to
TEST_DATABASE_URL when DATABASE_URL is absent, so alembic never
falls back to the hardcoded 'tod' URL in alembic.ini regardless
of which env var a test runner sets.
- tests/integration/conftest.py: add explanatory comments on why
DATABASE_URL is forced into the subprocess env, and use
env.setdefault() to supply CREDENTIAL_ENCRYPTION_KEY if the
calling environment omits it — migration 029 (VPN tenant
isolation) requires it to encrypt the WireGuard server private key.

sync_wireguard_config opens its own AdminAsyncSessionLocal connection
which cannot see uncommitted data from the caller's transaction. Add
_commit_and_sync helper that commits first, then regenerates wg0.conf.
Also removes the unused db parameter from sync_wireguard_config.
Tests subnet allocation (gap-filling, duplicate rejection), global
server key sharing, peer isolation across tenant subnets, allowed-IPs
overlap validation, RouterOS command generation, and CASCADE cleanup
on tenant deletion. sync_wireguard_config is patched to a no-op since
it opens its own DB session outside the test transaction.
