feat: Add PrismaCompatibleDate type and enhance date validation in photo extraction

Browse Source 
This commit introduces a new `PrismaCompatibleDate` type to ensure compatibility with Prisma's SQLite driver by storing dates in a DateTime format. Additionally, the `extract_exif_date`, `extract_video_date`, and `extract_photo_date` functions are updated to include validation checks that reject future dates and dates prior to 1900, enhancing data integrity during photo and video metadata extraction.
