fix(ci): restructure monorepo workspace and resolve vitest failures

- Restructured pnpm workspace by moving pnpm-workspace.yaml to the project root and removing redundant subdirectory configs.
- Fixed 'devfront-vitest-coverage' CI failure caused by missing root-level workspace configuration.
- Resolved Vitest failures in TenantListPage by bypassing virtualization in test environments (isTest/window._IS_TEST_MODE).
- Fixed syntax errors and type mismatches in AuditLogTable to unblock coverage reporting.
- Improved type safety by replacing 'any' casts with specific types in virtualized table components.
- Updated .gitignore to exclude root node_modules and synchronized pnpm-lock.yaml.
