feat(gateway): add all missing platforms to interactive setup wizard

[teknium1]

Summary

Wire all 6 missing platforms into the hermes setup gateway interactive wizard. These platforms all had working adapters and _PLATFORMS entries in gateway.py but were invisible in the setup checklist — users had to manually edit .env to configure them.

Platforms added to the wizard

• Signal — delegates to existing custom _setup_signal() in gateway.py
• Email — delegates to _setup_standard_platform() via _PLATFORMS entry
• SMS (Twilio) — delegates to _setup_standard_platform() via _PLATFORMS entry
• DingTalk — delegates to _setup_standard_platform() via _PLATFORMS entry
• Feishu / Lark — delegates to _setup_standard_platform() via _PLATFORMS entry
• WeCom (Enterprise WeChat) — delegates to _setup_standard_platform() via _PLATFORMS entry

Changes

hermes_cli/gateway.py (+30 lines)

• Added _setup_email(), _setup_sms(), _setup_dingtalk(), _setup_feishu(), _setup_wecom()
• Each looks up its _PLATFORMS entry and delegates to _setup_standard_platform()

hermes_cli/setup.py (+71 lines)

• 6 new wrapper functions delegating to their gateway.py counterparts
• _GATEWAY_PLATFORMS list expanded from 9 to 15 entries
• any_messaging check expanded to cover all platform env vars
• _get_section_config_summary expanded to show all configured platforms (was also missing Matrix, Mattermost, Weixin, and Webhooks)

website/docs/user-guide/messaging/index.md (+2 lines)

• Added FEISHU_ALLOWED_USERS and WECOM_ALLOWED_USERS to security allowlist examples
