Added Multi-Language Support:

Implemented a mechanism to detect the system language using environment variables (LANG, LC_ALL) on Linux and Unix-based systems. On Windows, the chcp command is used.
Supported languages include English, Turkish, Spanish, French, German, Chinese, and Japanese.
Translation JSON File:

Created a translations.json file containing translations for all supported languages.
The JSON file includes keys for various messages used in the script.

Translation Function:

Added a translate function to fetch the appropriate translation from the JSON file based on the detected system language.
The function uses jq to parse the JSON and retrieve the correct message.

Integrated Translations in Script:

Replaced hardcoded messages with calls to the translate function.
Ensured that all user-facing messages are translated according to the system language.
Example of Translated Messages:

Messages such as "Connected to L1 chain", "Waiting for L1 chain deployment data", and "Starting Fuel node" are now dynamically translated.

Improved User Experience:

Users will now see messages in their system's language, enhancing usability and accessibility.

- Integrated system language detection to determine the appropriate language for messages.
- Loaded translations from a JSON file based on the detected system language.
- Replaced echo statements with a translate function to fetch and display messages in the appropriate language.
- Added translations for English, Turkish, Chinese, Japanese, Spanish, German, and French.

…e server configuration

- Introduced dynamic HOST variable in app.ts to allow flexible server host configuration.
- Updated the server startup message to use the HOST environment variable.
- Ensured the server starts on the specified host from the environment variable, defaulting to 'localhost' if not set.
- Added HOST entries in the environment (.env) files.

Updated the BlockEntity class to use const for transaction mapping, ensuring values are not reassigned elsewhere in the code. This improves code reliability and maintainability by preventing unintended mutations.

Refactored the ChainEntity creation method to streamline the assignment of chainID and chainData. This improves readability by using clear variable names and structured data flow, enhancing code maintainability.
