refactor(provider): switch auth from password to API token

Prefer API token over username/password — scoped to least-privilege
TerraformRole, reduces blast radius if credentials leak.

+# Project: ProxmoxInfra
+
+Terraform infrastructure-as-code for a homelab Proxmox environment.
+
+## Context
+
+This repo was started *after* the Proxmox server was already set up manually.
+Existing infrastructure was provisioned by hand and must not be touched by
+Terraform. Only new resources going forward are managed here.
+
+## Key rules for this project
+
+- **Never import or manage existing Proxmox resources** unless the junior
+  explicitly decides to and understands the risk of state drift.
+- **Credentials never go in version control.** `.tfvars` files are gitignored.
+  Always use `terraform.tfvars.example` as the template pattern.
+- **No resources in root module.** As the repo grows, push toward a
+  `environments/` layout with reusable modules under `modules/`.
+- **State is not yet remote.** When a backend is introduced, make it a
+  deliberate decision with a knowledge transfer on why remote state matters
+  (locking, team access, DR).
+
+## Stack
+
+- Provider: `bpg/proxmox` (not the deprecated Telmate provider)
+- Terraform >= 1.0
+- Target: single-node Proxmox VE homelab
+
+## Learning goals for this project
+
+- Understand Terraform's core workflow (init / plan / apply / destroy)
+- Understand provider authentication and least-privilege API tokens
+- Understand state — what it is, why it matters, what happens when it drifts
+- Build intuition for when to use a VM vs an LXC container in Proxmox
+- Learn to structure a Terraform repo that can scale without becoming a mess
