fix: Fixed reference num and section generation issue

[AjitPadhi-Microsoft]

Purpose

• This pull request improves citation handling in answers, enhances error messaging for empty proposal sections, and updates the document generation button logic to prevent generating documents with no sections. Below are the most important changes grouped by theme:

Citation Handling Improvements

• Refactored the citation parsing logic in AnswerParser.tsx to reindex citations, remove invalid markers, and ensure only valid citations are displayed in the formatted answer text. This prevents duplicate and out-of-range citations from appearing in the UI.

Template Section Error Handling

• Added a new error message EmptySectionsError to contentTemplateSections in helpers.ts for cases when no sections are selected in a proposal.
• Updated generateTemplateSections in helpers.ts to return the new EmptySectionsError message if the template contains no sections, improving user feedback for empty proposals.

Document Generation Button Logic

• Modified the document generation button in Chat.tsx to be disabled if the draft document has no sections, preventing users from generating empty documents.

Does this introduce a breaking change?

• Yes
• No

Golden Path Validation

• I have tested the primary workflows (the "golden path") to ensure they function correctly without errors.

Deployment Validation

• I have validated the deployment process successfully and all services are running as expected with this change.

What to Check

Verify that the following are valid

• I have built and tested the code locally and in a deployed app
• For frontend changes, I have pulled the latest code from main, built the frontend, and committed all static files.
• This is a change for all users of this app. No code or asset is specific to my use case or my organization.
