feat: Paridad Excel-style AdvancedTable ↔ VirtualAdvancedTable

Propuesta Gemini: Unificación funcional entre tablas.

1. Modo inserción centralizado en NavigationState (table_core)
   - is_insertion_mode, last_inserted_id
   - enterInsertionMode(), exitInsertionMode(), isInInsertionMode()

2. Auto-edit en Ctrl+N (AdvancedTable)
   - Tras insertar fila, inicia edición inmediatamente en col 0

3. Auto-insert en Tab (Modo Pro)
   - En modo inserción, Tab al final de fila inserta nueva fila
   - Permite meter 50+ líneas sin soltar teclado

4. Fix ghost row clonada
   - Comparar row_id AND row_index en rendering
   - Evita que fila insertada y ghost row compartan buffer
