[FEATURE] table load with schema enabled lakehouses

Use Case / Problem

I gave command fab table load ..., but I get error "table load: [UnsupportedOperationForSchemasEnabledLakehouse] The operation is not supported for Lakehouse with schemas enabled".
I believe schema enabled lakehouses are the majority nowadays, so it would be nice to be able to do this with fab command instead of manually.

Proposed Solution

Not my expertise

Alternatives Considered

Manual upload

Impact Assessment

• This would help me personally
• This would help my team/organization
• This would help the broader fabric-cli community
• This aligns with Microsoft Fabric roadmap items

Implementation Attestation

• I understand this feature should maintain backward compatibility with existing commands
• I confirm this feature request does not introduce performance regressions for existing workflows
• I acknowledge that new features must follow fabric-cli's established patterns and conventions

Implementation Notes

No response

Start by reproducing the fab table load error against a schema-enabled lakehouse and trace the table-load command entry point. Determine the supported upload path for schema-enabled lakehouses while preserving existing behavior for other lakehouses; done means the command succeeds in both cases.
