Subject: [PATCH] Add automatic table creation to declaration create page

Database Fix:
- Added automatic table creation for missing tables
- Creates llx_declarationtva_declarations, llx_declarationtva_periods, llx_declarationtva_ca3_lines
- Matches the same approach used in setup_mvp.php
- Ensures all required tables exist before processing

This fixes the 'Table doesn't exist' error when creating declarations.
