Subject: [PATCH] Perf: Add composite database indexes for common queries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add indexes for:
- (AccountId, Category) - account spending by category
- (AccountId, Date) - account transaction timelines
- (MerchantId, Date) - merchant spending trends
- (CardId, Date) - card activity analysis
- FileHashSha256 on Receipts - duplicate detection
- (TransactionId, ReceiptDate) on Receipts - receipt lookups
