[anujeet98]

Changes:

• Refactored team-columns.tsx and member-columns.tsx to use the unified DataField component, ensuring consistent styling across organization views.
• Implemented AddColumnDialog modal to handle user interactions for creating new table columns.
• Updated the BaseTable component suite (Table, Header, Row, Cell, Body) to support "Add Row" and "Add Column" functionalities.
• Added support for rendering optional Avatars in TableFields.tsx instead of standard icons.
• Updated use-base-table.ts hook to manage column creation dialog states and S.No rendering.
• Updated types.ts and table-metadata.ts to include new interactive configuration properties for columns.
• Updated global table styles in table.tsx to improve alignment and interaction feedback.

Test Coverage:

• Updated member-management.spec.ts to validate member names instead of emails during the invitation process.
