Feat: add addressing style config for S3-compatible storage (#11510)

### Type of change
* [x]  New Feature (non-breaking change which adds functionality)


Add support for Virtual Hosted Style and Path Style URL addressing in
S3_COMPATIBLE storage connector. Default to Virtual Hosted Style for
better compatibility with COS and other S3-compatible services.

- Update frontend form with selection dropdown
- Add validation and tooltips for S3 Compatible endpoint URL
