Admin Applicants Table and Review Files

[adityapat24]

Goal

Create the admin applicants table, single-applicant detail page, decision/RSVP inline editors, and CSV export. No real logic yet, stubs only.

The shared (admin)/layout.tsx is created by Ticket 5. This ticket only adds applicants pages inside it.

Folders to create

• src/app/(admin)/admin/applicants/
• src/app/(admin)/admin/applicants/[id]/
• src/app/api/v1/applicants/[id]/
• src/app/api/v1/export/applications/
• src/app/api/v1/export/post-acceptance/
• src/lib/applicants/
• src/components/admin/applicants/
