Subject: [PATCH] Seed default category mappings on application startup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Added automatic seeding of default category mappings to ensure the
transaction categorizer has patterns to match against. This fixes the
issue where all transactions appeared as uncategorized during preview
because the CategoryMappings table was empty.
