`serverAuthSetup` runs twice for `mern+tailwind+auth` and `mevn+tailwind+auth` stacks

Bug

For the two *+tailwind+auth stacks, the Express server setup (which runs npm init -y and installs dependencies) executes twice:

1. Once inside the stack setup itself:
   • mernSetup() calls serverAuthSetup() when config.stack === "mern+tailwind+auth" (utils/installer.js:321-322)
   • mevnTailwindAuthSetup() calls serverAuthSetup() at the end (utils/installer.js:398)
2. Then again from utils/project.js:
   • mern+tailwind+auth path: project.js:204 → serverAuthSetup(...) after mernTailwindSetup
   • mevn+tailwind+auth path: project.js:210 → serverAuthSetup(...) after copyTemplates

Reproduction

1. celtrix create → stack mern+tailwind+auth
2. Observe npm init -y + dependency install output twice for the server/ directory

Impact

• Redundant npm init -y + full dependency install → noticeably slower scaffolding.
• Second npm init -y rewrites server/package.json (dependencies are dropped, then reinstalled) — wasteful and risks losing the deps between the two passes.

Suggested fix

Call serverAuthSetup in exactly one place per stack — either inside the *Setup helper or in project.js, not both. Prefer keeping it in project.js so the auth-server setup is uniform across stacks.

Environment

• celtrix v3.0.1

@JoeCelaster I would like to work on this issue.
