⚡ Bolt: Optimize redundant filter counts inside useMemo

[keerthivinod]

💡 What:

• Added a reduce() hook to accumulate dynamic counts up front rather than iterating with .filter().length on every category.
• Updated page.jsx, DashboardModule.jsx, MaintenanceModule.jsx, ProjectsModule.jsx, and ReportsModule.jsx.

🎯 Why:

• Repeating .filter(...).length calculations natively scales poorly when placed within .map() functions inside JSX, causing multiple redundant array traversals on every render.

📊 Impact:

• Reduces redundant list iterations per render from O(N*M) to a single O(N) initialization pass inside a useMemo hook, ensuring computations only occur when data actually changes.

🔬 Measurement:

• Changes verified manually through typescript syntax validation, full testing suite validation (19 tests passed), and code review logic checking to ensure mathematically identical status assignment fallbacks.
