Enhance database schema with photo-tag linkage type and remove redundant migrations

Browse Source 
This commit adds a new column, linkage_type, to the phototaglinkage table to distinguish between single and bulk tag additions. Additionally, the previous migration attempts to add date_taken and date_added columns to the photos table have been removed, streamlining the database initialization process. These changes improve the database structure for better tag management.
