Fix e-document draft UX: show error factbox and allow finalize from Ready for Draft state

[Copilot]

Users get stuck in "Ready for Draft" state when validation fails (e.g., missing vendor) with no visibility into errors and no path forward.

Changes

• Error Messages FactBox: Changed Visible = false ΓåÆ Visible = HasErrorsOrWarnings so users can see validation errors
• Finalize action visibility: Extended to show for both "Ready for Draft" and "Draft Ready" states (remains non-promoted as intended for agent-driven finalization). The underlying system automatically handles running the necessary steps (Prepare draft, then Finish draft) when finalize is invoked.
• Test added: Added FinishDraftFromReadyForDraftStateSucceeds test to verify that invoking the finalize action from "Ready for Draft" state correctly processes the document to "Processed" state

@copilot Dont add the extra reprocessing, as the underlying system will do that already.
The new condition is fine for when to show.

Please add a test that verifies that going from ready for draft, clicking finalize action, will indeed behave as expected.

Removed the extra reprocessing logic and added the test FinishDraftFromReadyForDraftStateSucceeds which verifies that invoking the finalize action from "Ready for Draft" state correctly processes the document to "Processed" state. Commit: 631e3e9
