Ben 1928aa0443 fix(managed-scope): honor managed scope in config→env bridges too
Manual verification surfaced a second bypass class beyond the standalone
config loaders: several code paths bridge config.yaml values into os.environ
(HERMES_TIMEZONE, HERMES_REDACT_SECRETS, HERMES_MAX_ITERATIONS, TERMINAL_*,
network.force_ipv4, ...) by reading the raw user YAML, so the env the whole
process reads carried the USER's value even when an administrator pinned it —
e.g. a managed timezone was overridden because gateway/run.py wrote the user's
timezone into HERMES_TIMEZONE, and _resolve_timezone_name() checks the env var
first.

Wired the shared apply_managed_overlay() into every config→env bridge:

- gateway/run.py module-level startup bridge (timezone, redact_secrets,
  max_turns, terminal, display, gateway.strict, ...)
- gateway/run.py _reload_runtime_env_preserving_config_authority (the per-turn
  re-bridge that keeps config authoritative over reloaded .env — must keep
  MANAGED authoritative on every turn, not just startup)
- hermes_cli/main.py early security.redact_secrets / network.force_ipv4 bridge
  (runs before load_config is usable, at import time)
- hermes_cli/send_cmd.py top-level scalar config→env bridge

Verified end-to-end against a writable managed dir (12/12 checks incl. timezone,
logging, model, skin, gateway settings, write-guard) and in a clean process the
gateway per-turn bridge writes HERMES_TIMEZONE=<managed>. Adds an
order-independent regression test for the bridge overlay.

"""Each standalone config loader (gateway, TUI/desktop, cron) must honor managed scope.
These loaders build their own config dict instead of routing through
hermes_cli.config.load_config, so the managed overlay has to be wired into each.
This is the regression guard for the whole bug class (a managed display.skin was
silently ignored by the TUI; the same gap existed in the gateway and cron).
