fix: remove LANGSMITH_TRACING override that ignores .env value (#1640)
The `environment` section in docker-compose.yaml set
`LANGSMITH_TRACING=${LANGSMITH_TRACING:-false}`, which always resolves
to `false` because Docker Compose evaluates `${}` substitutions from
the host shell environment, not from `env_file`.

Since `environment` entries take precedence over `env_file`, setting
`LANGSMITH_TRACING=true` in `.env` had no effect — tracing stayed
disabled despite following the documented instructions.

Remove the explicit `LANGSMITH_TRACING` from `environment` so the
value from `.env` (loaded via `env_file`) is used as intended.
