fix(monitor): complete the missing help links in the monitoring template

[P-Peaceful]

What's changed?

• Added missing helpLink entries to 11 monitoring templates:
  • Dahua
  • DNS
  • Hikvision ISAPI
  • Memcached
  • Modbus
  • NTP
  • Registry
  • S7
  • SMTP
  • Uniview
  • WebSocket
• Added localized help links for both Chinese and English documentation.
• The S7 monitoring documentation is not available yet. It will be completed and submitted in a follow-up PR.
• This allows users to access the corresponding monitoring documentation directly from the monitoring configuration interface.

Testing

Not run. This is a configuration-only change that adds documentation links to monitoring templates.

Follow-up

The S7 monitoring help documentation is currently unavailable. I will add the missing S7 documentation in a subsequent PR.

Straightforward config-only change that adds missing helpLink entries to 11 monitoring templates, consistently following the existing zh-CN/en-US-only pattern seen in templates like app-linux.yml. The only concern is the S7 link pointing to documentation that doesn't exist yet.

[utafrali]

The S7 help documentation doesn't exist yet (acknowledged in the PR description), so both URLs here will return 404 until the follow-up PR lands. A dead link is a worse user experience than no link at all. Consider one of these approaches:

1. Drop the helpLink block from this file now and add it in the same PR that ships the S7 docs.
2. Or, if the docs page already exists in draft/stub form, verify the URLs resolve before merging.
