Add Authentik OIDC SSO as the default human login for OpenBao (#147)
## Why

Human login to OpenBao is LDAP-only, so operators keep a second credential set outside Authentik and group membership is maintained twice.

## How

- Add `auth_oidc_backend` module: `oidc`-type JWT auth mount, Authentik discovery URL, `listing_visibility: unauth`, credentials from `kv/service/authentik/oidc-vault`.
- Add `auth_oidc_role` module: oidc role with `user_claim` email, `groups_claim` `ak_groups`, scopes `openid profile email ak_groups`, the registered redirect URIs, `bound_audiences` `[vault]`.
- Add `auth_oidc_group` module: external identity group plus group alias on the OIDC mount accessor, policies from `policy_auth_map`.
- Add config under `config/auth_oidc_{backend,role,group}/`, discovery locals in `config/config.hcl`, `vault_cluster` variables and wiring, and terragrunt inputs.
- Bind `akP-vault-admin` on the `oidc` mount to `global-root`, alongside the existing LDAP `vault_admin` binding.
- Pin the mount path to the literal `oidc`: the registered redirect URIs embed `/ui/vault/auth/oidc/oidc/callback`.

Requires #146, terraform-authentik #33 and #148 applied first.

# =============================================================================
# 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
#
