fix: comprehensive CI resolution and security hardening

Resolved multiple CI failures and security scan violations:
- Fixed Deno 'no-explicit-any', 'require-await', 'no-unused-vars', and 'no-window' errors in 'next-app', 'frontend', and 'backend' modules.
- Surgically refactored 'rag-agentic-dashboard/server.js' to ensure unique imports and proper application of 'express-rate-limit'.
- Hardened the confidential enclave Terraform blueprint by enabling detailed monitoring and configuring a non-default VPC (subnet-id) to satisfy security gates.
- Standardized Netlify '_headers' and '_redirects' files to ensure exact formatting and removal of trailing whitespace.
- Synchronized all Netlify configuration files between the root and 'next-app/public/' directories.

All daily GSIFI governance checks and artifact validations (G-SRI, attestation) are passing.
