feat(ci): add skip Nx cache option to workflows

Add workflow_dispatch input to force fresh builds without Nx cache:
- deploy-dev.yml: Add skip_nx_cache boolean input
- nx-optimized-ci.yml: Add skip_nx_cache boolean input
- Both workflows now support --skip-nx-cache flag
- Also supports NX_SKIP_NX_CACHE environment variable

This provides multiple ways to troubleshoot CI cache issues:
1. Manual workflow dispatch with 'Skip Nx cache' checkbox
2. Force build all sites option (already existed)
3. Environment variable for debugging

Fixes CI build failures caused by corrupted Nx Cloud cache.
