Function resolveCreateAtVersion

resolveCreateAtVersion(
    flags: CreateFlags,
    config?: DynamodbPluginConfig,
    ref?: ProcessEnv,
): ResolvedCreateAtVersion
Resolve CLI flags + plugin config into create-table inputs for a specific version.

Expansion policy:
- Config strings are already interpolated by the host (do not re-expand).
- Runtime flags are expanded once using get-dotenv's dotenvExpand.
- Expansion reference is { ...process.env, ...ref } (ctx wins).
Parameters
- flags: CreateFlags
  Parsed CLI flags.
- Optionalconfig: DynamodbPluginConfig
  Plugin config slice (already interpolated by host).
- ref: ProcessEnv = process.env
  Env reference (typically ctx.dotenv).
Returns ResolvedCreateAtVersion
Resolved version, layout config, and create options.
