chore: replace codebase with Next.js version (console-new)

[overtrue]

Replace the existing Nuxt/Vue console with the Next.js/React version (console-new). This PR is a full codebase migration: same feature set and i18n structure, new stack (Next.js 16, React 19, App Router) and simplified GitHub templates.

• Stack: Nuxt 3 + Vue 3 → Next.js 16 + React 19
• Routing: Vue Router / file-based pages → App Router (app/(auth)/, app/(dashboard)/)
• State: Composables → React hooks + contexts (e.g. use-bucket, auth-context, s3-context)
• UI: shadcn-vue → shadcn (Radix) + Tailwind
• CI: .github/ workflows and templates copied from old project, build workflow adapted for Next.js (.next output); PR/issue templates simplified (no emoji, fewer sections)

Existing main is backed up as backup/main. This PR does not change backup/main or dev.

Checklist

• Code follows the project's style guidelines
• Self-review completed

Screenshots (if applicable)

N/A — same UI/UX as before; layout and flows preserved.

Additional Notes

• Recovery: Previous Nuxt codebase remains on branch backup/main.
• Branch strategy: After merge, main will be the Next.js app; dev can be updated from local console-new via git push origin main:dev or by syncing with main.
