refactor(api): streamline mikrotik-install script and enhance synchronization logic

- Consolidated the `mikrotik-install.rsc` script to utilize a single `evofw-sync` script for improved clarity and efficiency in synchronization processes.
- Removed the legacy `evofw-env` script, simplifying the token management and ensuring a more reliable update mechanism.
- Updated the token generation logic to enhance security and reliability, while ensuring compatibility with RouterOS 7+.
- Adjusted test assertions in `install-links.test.ts` to verify the presence of new script components and ensure accurate testing of the installation logic.

These changes improve the overall robustness and maintainability of the agent installation and synchronization process.
