vault: wire up ghp secrets engine (backend + role + policies) (#121)
Why: final step of the ordered ghp plugin add. Mounts + configures the ghp OpenBao secrets engine and its token-minting role (catalog registration is #123; policies #122).

How: config/ghp_secret_backend/ghp.yaml (mount at ghp; base_url https://ghp.unkin.net; admin_token read from KV kv/service/vault/au/syd1/secret_backend/ghp/config), config/ghp_secret_backend_role/ghp/agent.yaml (agent role), the two vault_cluster submodules, and the config.hcl ghp_secret_backend/role discovery + terragrunt inputs pulling the ghp provider (vault-secrets-ghp v0.1.0).

ORDER — apply in sequence:
1. puppet-prod#520 — install openbao-plugin-secrets-ghp binary (merged).
2. terraform-vault#122 — config-write policy (merged).
3. terraform-vault#123 — register plugin in catalog.
4. THIS PR — mount + config + role.

Before apply is clean: set the role real ghp App installation_id (currently sentinel 0), and KV dual-seed the ghpsvc_ token (this engine admin_token + the ghp deployment GHP_AUTH_SERVICE_TOKENS).

# =============================================================================
# VAULT MODULE CONFIGURATION SYSTEM
# =============================================================================
#
# This file automatically discovers and organizes YAML configuration files
# for Vault modules, creating structured configuration maps for Terraform.
#
# HOW IT WORKS:
# 1. Scans all subdirectories for *.yaml files
# 2. Groups files by module type based on directory structure
# 3. Creates unique resource keys to prevent naming conflicts
# 4. Adds computed fields like name, backend, etc. from file paths
#
# DIRECTORY STRUCTURE:
# config/
# ├── auth_approle_role/
# │ └── approle/
# │ ├── certmanager.yaml # Creates key: "approle/certmanager"
# │ └── myapp.yaml # Creates key: "approle/myapp"
# ├── auth_kubernetes_role/
# │ └── k8s/au/syd1/
# │ ├── default.yaml # Creates key: "k8s/au/syd1/default"
# │ └── myapp.yaml # Creates key: "k8s/au/syd1/myapp"
# └── kv_secret_backend/
# ├── kv.yaml # Creates key: "kv"
# └── secrets.yaml # Creates key: "secrets"
#
# EXAMPLE YAML FILE (config/auth_approle_role/approle/myapp.yaml):
# ```yaml
# token_ttl: 3600
# token_max_ttl: 7200
# bind_secret_id: true
# token_bound_cidrs:
# - "10.0.0.0/8"
# ```
#
# This becomes:
# ```hcl
# auth_approle_role = {
# "approle/myapp" = {
# approle_name = "myapp" # Auto-computed from filename
# mount_path = "approle" # Auto-computed from directory
# token_ttl = 3600 # From YAML content
# token_max_ttl = 7200 # From YAML content
# bind_secret_id = true # From YAML content
# token_bound_cidrs = ["10.0.0.0/8"]
# }
# }
# ```
#
# KEY NAMING PATTERNS:
# - Simple backends: filename only (e.g., "kv", "transit")
# - Role-based resources: full path without extension (e.g., "approle/myapp")
# - This ensures uniqueness when multiple backends have similar role names
#
# GENERATED OUTPUTS:
# - config.auth_approle_backend, config.auth_approle_role, etc.
# - Each module gets its own map with properly structured configuration
#
