Refactor database interface to use *sql.DB directly

Simplified the database layer by removing custom interface wrappers and using standard library *sql.DB and *sql.Tx types directly. Changes: - Removed DBConnection and DBTransaction interfaces from database.go - Removed NewDBConnection() wrapper function - Updated TokenGenerator to use *sql.DB instead of DBConnection - Updated all validation and revocation methods to accept *sql.Tx - Updated TableManager to work with *sql.DB directly - Updated all tests to use db.Begin() instead of custom wrappers - Fixed GeneratorConfig.DB field (was DBConn) - Updated documentation in doc.go with correct API usage Benefits: - Simpler API with fewer abstractions - Works directly with database/sql standard library - Compatible with GORM (via gormDB.DB()) and Bun (share same *sql.DB) - Easier to understand and maintain - No unnecessary wrapper layers Breaking changes: - GeneratorConfig.DBConn renamed to GeneratorConfig.DB - Removed NewDBConnection() function - pass *sql.DB directly - ValidateAccess/ValidateRefresh now accept *sql.Tx instead of DBTransaction - Token.Revoke/CheckNotRevoked now accept *sql.Tx instead of DBTransaction 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
