Refactor dependency handling and enhance user management features

[prinako]

This pull request introduces a new API endpoint and supporting backend logic to fetch multiple users by their Telegram IDs, and refactors the AgendaPayment class in the Telegram bot to use a more modular, handler-based approach for processing keyboard interactions. It also updates some dependencies and makes minor improvements to Dockerfile and package management.

Backend: Multi-User Fetching by Telegram IDs

• Added a new API endpoint /api/users-ids/:telegramIds and supporting controller, service, and repository functions to retrieve multiple users by their Telegram IDs. This includes getByTelegramIds in the controller, getUsers in the service, and getUsersByTelegramIds in the repository. [1] [2] [3] [4]
• Updated exports and imports across backend files to support the new multi-user functionality. [1] [2] [3] [4] [5]
• Added a placeholder getUsers function in the bot's backend client for future use.

Bot: Refactoring AgendaPayment Keyboard Handling

• Refactored the AgendaPayment class to use a handler pattern for keyboard interactions, improving code readability and maintainability. Each keyboard action (e.g., member toggle, month selection, bank selection) now has its own method. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11]
• Improved error handling and separation of concerns for bank selection and picker display. [1] [2]

Dependency and Build Improvements

• Updated dependencies in tele_bot/package.json to newer versions for dotenv, node-cron, and node-telegram-bot-api.
• Improved Docker build context in tele_bot/Dockerfile for more precise copying of files and directories.

Other

• Removed the root-level package.json, possibly as part of a project structure cleanup.
