Hardcoding the JWT secret key can lead to arbitrary users spoofing tokens.

[Redpeppersir]

Description: Hardcoding the JWT secret key can lead to arbitrary users spoofing tokens. Since the travels-java-api is an open-source project, others can easily obtain the JWT secret key of travels-java-api. This allows them to use the JWT secret key to generate arbitrary JWT tokens and gain access to any user's permissions.

Fix Suggestion: Generate a random JWT secret key during project initialization and store it in the database.
