+fix(app-shell): readable option labels for unlabeled datasource enum selects (objectui#13353)
+
+Setup → Datasources: a driver-config JSON Schema `enum` select showed each raw value (`off`, `safe`) as its option text. The driver-config schema declares no per-option label, so each option's text is now built from its raw value with Studio's `humanizeKey`, the helper `SchemaForm`'s enum selects already use (`off` → "Off", `read_only` → "Read Only", `fullSync` → "Full Sync"). The value the form saves stays the raw enum member.

+ * objectui#13353 — a driver-config `enum` select shows readable option text.
+ *
+ * The create/edit dialog builds its config form from the driver catalog's JSON
+ * Schema (`GET /api/v1/datasources/drivers`). An `enum` property carries no
+ * per-option label (no carrier exists in the driver-config schema today), and
+ * each option rendered `String(opt)`, so the SQL drivers' `autoMigrate` select
+ * offered the bare words `off` and `safe`. Each option now shows a label built
+ * from its raw value with Studio's `humanizeKey` (the same helper `SchemaForm`'s
+ * enum selects use), while the value the form saves stays the raw enum member.
