Add Pulumi for tailnet IaC management (#15)

## Summary
- Manage tail8d86e.ts.net ACLs, tags, and DNS via Pulumi + Python
- State stored in Pulumi Cloud (free tier) to avoid circular dependency
- OAuth authentication via 1Password for secure credential management
- New mise tasks: `tailnet-preview`, `tailnet-up`

## Architecture
Two-layer approach:
- **Layer 1 (Pulumi)**: Tailnet-wide config (ACLs, tags, DNS)
- **Layer 2 (Ansible)**: Node-local `tailscale serve` config (unchanged)

## Test plan
- [x] Exported current ACL from Tailscale API
- [x] Imported existing ACL into Pulumi state
- [x] Verified `mise run tailnet-preview` shows no changes
- [x] Verified `mise run tailnet-up` applies successfully
