docs: Update CLAUDE.md with data-entry-app references

- Add application-specific instructions section
- Reference data-entry-app/CLAUDE.md for data entry work
- Update architecture diagram with both apps
- Add starting services commands for both apps
- Add data-entry documentation to Documentation Index
- Clarify when to use which instructions

+## 📁 Application-Specific Instructions
+
+> **IMPORTANT**: When working on a specific application, ALWAYS read its dedicated CLAUDE.md first!
+
+| Application | CLAUDE.md Location | Description |
+|-------------|-------------------|-------------|
+| **Data Entry** | `data-entry-app/CLAUDE.md` | Bonuri fiscale, chitanțe, workflow aprobare |
+| **Reports** | This file (below) | Rapoarte Oracle read-only |
+| **Telegram Bot** | `reports-app/telegram-bot/README.md` | Bot Telegram |
+
+### When to Use Which Instructions
+
+**Working on `data-entry-app/`**:
+→ **FIRST read `data-entry-app/CLAUDE.md`** for:
+  - SQLModel + Alembic patterns (NOT Oracle)
+  - SQLite database (NOT Oracle pool)
+  - Workflow states (DRAFT → PENDING → APPROVED)
+  - Receipt/Attachment/AccountingEntry models
+  - Expense types and auto-generation logic
+
+**Working on `reports-app/` or `shared/`**:
+→ Use instructions from this file (below)
+
+**Working on shared components** (`shared/auth/`, `shared/database/`):
+→ These are used by BOTH apps - be careful with changes!

 ### Key Architectural Decisions
 - **Shared Database Pool**: Singleton `OraclePool` in `shared/database/oracle_pool.py` (python-oracledb with connection pooling)
 - **Centralized Auth**: JWT-based auth in `shared/auth/` with middleware auto-injecting `request.state.user`
