💡 What:
Added a prepareSearchIndex function to pre-calculate derived search properties (_searchStr, _formattedDate, and _isNew) on initial data load, and refactored the filter loop in renderPDFs to use early returns.

🎯 Why:
Filtering and rendering loops for large lists of objects were suffering from repetitive, expensive inline calculations (string concatenations, toLowerCase calls, and Date object instantiations). Pre-calculating these values significantly reduces processing time per render cycle.

📊 Impact:
Massive reduction in CPU overhead during typing and filtering. Replaces repeated expensive object allocations and regex/string scans with simple string and boolean checks.

🔬 Measurement:
Tested locally using Playwright with a populated cache. Verified that list filtering using the pre-calculated _searchStr functions correctly without errors and gracefully handles legacy/unindexed objects via fallbacks.

This patch addresses a performance bottleneck where derived properties
(_searchStr, _formattedDate, _isNew) were being repeatedly calculated
during high-frequency render and filter loops.

By pre-calculating these properties in a new `prepareSearchIndex` function
immediately after data fetch and caching, and converting sequential
boolean conditions into early returns, we achieve significant UI speedups
when rendering and filtering large lists.
