vault: mount arrstack engine + config + roles (3/3) (#127)
## Why

Creates the arrstack secrets engine itself: the mount + config and the per-scope roles that mint arrproxy API keys. **PR 3 of 3 (resources)**, stacked on #126 (policy). Final step of the register -> policy -> resources split (was #124).

## Change

- Adds `config/arrstack_secret_backend/arrstack.yaml`: mounts the engine at `arrstack` and writes its config (`base_url`, timeout). The arrproxy admin token stays out of git and is read from KV by the module.
- Adds `config/arrstack_secret_backend_role/arrstack/{all,sonarr,radarr,prowlarr}.yaml`: roles scoped to each arr app (plus one covering all three). Default `ttl` is **60s** (short-lived, renewed on demand); `max_ttl` 86400 mirrors the litellm sibling convention. The engine additionally caps renewal at the arrproxy admin token's fixed mint expiry.
- Adds `modules/vault_cluster/modules/arrstack_secret_backend{,_role}` and wires them in: `config/config.hcl` maps, `modules/vault_cluster/main.tf`, `variables.tf`, the environment inputs, and the root provider block.
- Provider source is `artifactapi.k8s.syd1.au.unkin.net/terraform-unkin/vault-secrets-arrstack` (repo `terraform-provider-vault-secrets-arrstack`), local name `arrstack`.

## Apply order

Apply **after PR #126 (policy) AND after `terraform-provider-vault-secrets-arrstack` v0.1.0 is published** to the artifactapi terraform registry. Until the provider is published, `tofu init` cannot resolve it, so **CI/plan on this PR is red by design** — that is expected, not a regression.

Note **plan-green != apply-green**: the KV-sourced `admin_token` is only fetched at apply time, so a green plan does not prove the seeded token is readable.

## Stack

1. register -> #125
2. policy -> #126
3. **resources (this PR)** -> `benvin/arrstack-resources` off `benvin/arrstack-policy`

Supersedes #124.

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