Subject: [PATCH] Fix migration 0001_initial: double CREATE TYPE crashes every
 clean bootstrap

world_visibility and asset_type were each declared twice: once explicitly
via `.create(checkfirst=True)`, and again implicitly by SQLAlchemy when
create_table() compiled the inline postgresql.ENUM() column type (which
defaults create_type=True). On a genuinely empty database this raises
asyncpg.DuplicateObjectError mid-transaction and the migration never
completes -- verified this was true 100% of the time from a fresh
container, meaning the backend has never successfully bootstrapped from
scratch. Fixed by passing create_type=False on the inline column
declarations, since the type is already created explicitly above.

Also parameterized both services' host ports (POSTGRES_HOST_PORT /
REDIS_HOST_PORT, defaulting to the original 5432/6379) so concurrent
agent workspaces sharing this same docker-compose.yml can run isolated
databases without colliding on the host port.
