`main()` routes the `connector` subcommand group straight to
`_dispatch_connector`, which — unlike the interactive TUI — never runs
preflight, so nothing populated `os.environ` from `~/.vibe-trading/.env`.
`EnvConfig` reads only `os.environ`, so every connector resolving
credentials through `get_env_config()` reported them as missing despite a
valid file on disk: Longbridge's app key / secret / access token (the only
broker credential set sourced from env vars rather than a JSON config
file), and Futu's `FUTU_TRADE_PWD_MD5` live-unlock hash.
Call the existing `_ensure_cli_env()` helper at the dispatcher entry.
`_ensure_dotenv()` is idempotent and loads with `override=False`, so a real
environment variable still outranks the file, and connectors that read JSON
config are unaffected.
Distinct from #477 / #541, which were the stale-`EnvConfig`-singleton
variant: there `_ensure_dotenv()` ran but no `reset_env_config()` followed.
Here it never ran at all, so that fix could not reach this path.
Closes#901
