+fix `db studio` for table and column names containing spaces
+
+The studio API rejected any identifier that didn't match
+`[a-zA-Z_][a-zA-Z0-9_]*`, returning a 400 "Invalid table name" for
+tables or columns with spaces. Replaced the validation with safe
+double-quote identifier escaping so any SQLite-valid name works.
