refactor: migrate from ESLint to Biome and extract SQL queries to data.ts

- Replace ESLint with Biome for linting and formatting
- Configure Biome with tabs, double quotes, and organized imports
- Move all SQL/Drizzle queries from page.tsx files to data.ts files
- Create new data.ts files for: ajustes, dashboard, relatorios/categorias
- Update existing data.ts files: extrato, fatura (add lancamentos queries)
- Remove all drizzle-orm imports from page.tsx files
- Update README.md with new tooling info
