fix(payroll): Refactor /collect endpoint and add To-Do.md

This commit addresses several issues in the `/collect` endpoint to improve its security and robustness. It also introduces a `To-Do.md` file as requested by the user.

Key changes:
- Refactored the `/collect` endpoint to use a single database transaction, preventing data inconsistencies.
- Fixed SQL injection vulnerabilities by converting all database queries to use parameterized statements.
- Corrected a `TypeError` by ensuring the `COLLECT_COOLDOWN` configuration variable is always an integer.
- Updated transaction logging to record 'SYSTEM' as the source of funds for salary collections, instead of a "NULL" string.
- Added a `To-Do.md` file with suggestions for future features, including an automated payroll system, user transaction history, and an admin panel.

+# Project To-Do and Feature Ideas
+
+This file tracks potential new features and improvements for the Interbend banking system.
+
+## Feature Suggestions
+
+1.  **Automated Payroll System:**
+    *   **Description:** Instead of requiring users to manually call the `/collect` endpoint, a scheduled script could run periodically (e.g., every 24 hours) to automatically distribute salaries to all eligible users.
+    *   **Benefits:** Improves user experience, ensures consistent pay, and reduces repeated API calls to the server.
+
+2.  **User Transaction History:**
+    *   **Description:** Create a new API endpoint (e.g., `GET /transactions`) that allows an authenticated user to retrieve a paginated list of their own transaction history.
+    *   **Benefits:** Provides users with transparency and a way to track their finances, which is a core feature of any banking application.
+
+3.  **Comprehensive Admin Panel:**
+    *   **Description:** Develop a simple web-based dashboard for administrators. This would be more user-friendly than using API endpoints for administrative tasks.
+    *   **Features:**
+        *   View and manage all users (e.g., edit balance, change job, view profile).
+        *   Manage jobs and their corresponding salaries.
+        *   View system-wide transaction logs and financial statistics.
+        *   A secure login system for administrators.
+    *   **Benefits:** Greatly simplifies the management of the roleplay economy and provides better oversight.
