### 🧩 Problem
- Tables **without primary keys** were previously selectable in the form
generator, leading to issues with data operations that require unique
identifiers.
- **Snowflake datasources** defaulted to `READ_ONLY` mode, unnecessarily
limiting users from performing query generation operations.
---
### ✅ Solution
- Disabled selection of tables that **lack primary keys** in the form
generator dropdown.
- Added **tooltips and helper text** to explain why certain tables are
disabled.
- Updated the **Snowflake query generator** to default to `READ_WRITE`
mode.
- Improved UI components to:
- Gracefully handle disabled options
- Clearly communicate restrictions to users
---
### 💡 Why This Solution Works
- Prevents users from selecting **invalid or unsuitable tables**,
reducing runtime errors.
- Improves the **user experience** through helpful visual cues and
explanations.
- Aligns Snowflake’s behavior with user expectations for **write
capabilities**.
- Maintains **backward compatibility** for both new and existing
configurations.
