fix(fabric): align chaincode vault secret paths

[malsomesh9]

Summary

Align the Fabric chaincode lifecycle job templates with the Vault secret path layout used by deployed peer nodes.

Changes

• update chaincode install, approve, commit, instantiate, upgrade, invoke, and external install job templates
• switch admin and orderer secret prefixes from the old peerOrganizations-based layout to the env-scoped data/ layout already used by peer deployments
• keep the fix scoped to the templated Vault paths used by the chaincode lifecycle jobs

Verification

Validated the rendered template inputs so the chaincode lifecycle jobs now use the same env-scoped Vault prefixes as value_peer.tpl.

Fixes #2624
