- Rewrite db.md as canonical schema: add categories, sessions tables; add alias to accounts, is_category_confirmed/comment to transactions, FK references to categories(id); mark budgets as post-MVP
- Fix account masking to use fixed 6 asterisks (code + docs)
- Remove budgets from MVP requirements in agent_backend.md
- Add explicit 'not in MVP' note to analytics.md budgets section
- Fix test_Statement.json: convert amounts to kopecks (integers), remove fingerprint fields (computed by backend)
