fix(db): update prefix handling in module_prefix_snapshot_row

Modified the prefix column type in the module_prefix_snapshot_row table to TEXT, allowing for more flexible input. Adjusted related SQL queries and Go struct tags to ensure compatibility with JSON serialization. Cleaned up migration logic to handle prefix and community_id fields more robustly.
