fix: move lexical declarations outside case blocks in AbsurdSqlDatabaseService

- Move queryResult and allResult declarations outside switch statement
- Change const declarations to let since they're now in outer scope
- Remove const declarations from inside case blocks

This fixes the 'no-case-declarations' linter errors by ensuring variables
are declared in a scope that encompasses all case blocks, preventing
potential scoping issues.

Note: Type definition errors for external modules remain and should be
addressed separately.
