sqlite: prevent database close during callbacks

[mcollina]

Prevent DatabaseSync.close() from finalizing SQLite resources while a JavaScript callback is executing.

SQLite invokes user-defined functions, aggregate functions, authorizers, and changeset callbacks synchronously during database operations. Previously, calling database.close() from one of these callbacks could finalize active statements or the connection while native code was still using them.

This change tracks callback depth and rejects reentrant closes with ERR_INVALID_STATE. It also adds regression coverage for StatementSync.all(), get(), run(), and iterate().
