fix: prevent leaked DB connection on vault operations after Close

VaultBackend.open() now checks for a nil passphrase before opening a new
SQLite connection. Previously, calling Set/Get after Close() would open
a new DB connection that was never closed, leaking the file handle. On
Windows, this caused t.TempDir() cleanup to fail because the vault.db
file was still locked by the leaked connection.
