Pull Request Description

This PR cleans up some of the logic surrounding database initialization/setup:

• Updated drift and related packages
• Cleaned up database initialization logic (for mobile/web implementations)
• Re-exported schema versions and migrated them into lib/src/core/database/schemas
• Added migration tests for each version upgrade
• Updated the web build to work properly with the database changes

This PR also removes the SQLite → Drift migration that was introduced in v0.3.0 (Apr 10, 2024). The goal here is to reduce tech debt by eliminating the need to maintain this transition logic as we make more changes to the database. This does mean that users upgrading directly from v0.2.9 to v0.8.0 will not have their data automatically migrated.
