What: Pre-calculated searchable fields (_searchStr), formatted dates (_formattedDate), and "is new" status (_isNew) directly onto the pdfDatabase objects in a new prepareSearchIndex function immediately following the database load. Removed duplicate date calculations and lowerecased string concatenations from the renderPDFs loop and createPDFCard generation.

Why: The renderPDFs search loop and createPDFCard DOM rendering ran expensive string lowercase logic, regular expressions, and new Date() parses for every card, every time the search input changed.

Impact: Significant reduction in CPU time during high-frequency events like typing in the search box. Reduces GC pressure by avoiding the allocation of temporary Date objects inside loops.

Measurement: Search responsiveness during typing should be visually improved, especially as the number of PDFs in the database grows. Tested manually and verified via local Playwright frontend test (checking renderPDFs).
