Remove cloudposse/template provider; migrate to templatefile() (#60)

* Remove cloudposse/template provider; migrate to templatefile()

Replace the deprecated `data "template_file"` user-data rendering with the
core `templatefile()` function and drop the `cloudposse/template` provider
from `required_providers`. Also bumps Go test module to 1.26.1 and refreshes
all test dependencies.

* Gate templatefile() behind local.enabled

Preserve the disabled-path behavior of the original `data "template_file"`
resource, which was scoped via `count = local.enabled ? 1 : 0`. The `local`
is now only evaluated when the component is enabled, avoiding potential
plan-time failures when `var.user_data` is unset in disabled deployments.

* Bump cloudposse/stack-config/yaml remote-state module to 2.0.0

The v1.8.0 module pinned `cloudposse/utils` to `>= 1.7.1, < 2.0.0`, which
conflicts with modern components that require `utils >= 2.0.0`. v2.0.0 of
the remote-state module pins `utils >= 2.0.0, < 3.0.0`, resolving the
`terraform init` provider-resolution failure.

* Bump vendored test fixture components to modern versions

Point `account-map` at `cloudposse-terraform-components/aws-account-map`
v1.537.2 (instead of the old monorepo `terraform-aws-components` 1.520.0
which used stack-config 1.5.0 → pinning utils < 2.0.0). Point `vpc` at
aws-vpc v2.2.0 (from v1.536.0). Both modern versions use
`cloudposse/stack-config/yaml//modules/remote-state` 2.0.0, which pins
`cloudposse/utils >= 2.0.0, < 3.0.0` — compatible with the bumped src.
