Typo: SymphonyDataHandlerCofig / syphonyExtendedVersionSpace

## Description

The Symphony data-handler Spring `@Configuration` class is misspelled as `SymphonyDataHandlerCofig` (should be `Config`). The helper method `syphonyExtendedVersionSpace()` is similarly misspelled (`syphony` → `symphony`).

## Location

- `libs/symphony-bdk/symphony-bdk-chat-workflow-spring-boot-starter/src/main/java/org/finos/springbot/symphony/data/SymphonyDataHandlerCofig.java`
- Referenced from `SymphonyWorkflowConfig` and several Symphony starter tests

## Impact

Cosmetic / discoverability only — behavior is fine, but the name is inconsistent with other `*Config` classes and harder to find when searching.

## Proposed fix

Rename:

- `SymphonyDataHandlerCofig` → `SymphonyDataHandlerConfig`
- `syphonyExtendedVersionSpace` → `symphonyExtendedVersionSpace`

Update imports/usages accordingly.

Start with libs/symphony-bdk/symphony-bdk-chat-workflow-spring-boot-starter/src/main/java/org/finos/springbot/symphony/data/SymphonyDataHandlerCofig.java and inspect its references from SymphonyWorkflowConfig and the Symphony starter tests. Rename the class and helper method, update all imports and usages, then run the affected starter tests. Done means the corrected names compile and no old spellings remain in the referenced code.
