Campaign detail: fix customer link pointing to ERPNext instead of Ops

The recipient row's customer link was href="/#/clients/<id>" — with the app on
hash routing served under /ops/, a leading slash before # resolves against the
site root, dropping /ops/ and landing on ERPNext desk. Drop the leading slash
so it stays scoped under the current /ops/ path.
