feat(database): update database schema for new features

- Rename tables and columns to better reflect their content and usage
- Add new columns for upcoming features like ad config and account action config
- Remove unused columns to simplify the schema
- Adjust foreign key relationships to match new table names
"""

Changed database schema to support new features and improve data organization. Here are the key changes:

- Renamed 'app_config' to 'remote_config' to clarify its purpose
- Renamed 'categories' to 'topics' to better reflect the content
- Removed 'type' columns from multiple tables as they were no longer used
- Added new columns to 'remote_config' for ad config, account action config, and app status
- Changed 'categories' to 'topics' in the 'headlines' table
- Removed 'last_engagement_shown_at' from 'users' table
- Updated table and column names to align with new feature requirements
