Backend: - Add POST /api/favorites/batch endpoint (single multi-row INSERT) - Add BatchFavoritesResult/BatchFavoritesStats DTOs - Add batch methods to ports, service, PG repository - Transaction-based insert with ON CONFLICT DO NOTHING, chunking at 5000 Frontend: - Rewrite batchFavorites() to single API call (40 requests → 1) - Add _replaceCacheFromResponse() to avoid extra GET round-trip - Centralize formatFileSize, isTextViewable, formatDateTime, formatDateShort - Remove duplicate icon mapping from app.js - Fix inconsistent quota defaults (10GB everywhere)
Standardize code formatting across all 173 Rust source files using rustfmt. No functional changes - purely cosmetic. This establishes a consistent code style baseline for the project going forward.
