Implement a caching mechanism for retrieving and storing user information.

[DiTsi]

A persistent cache for user details (get_user_details()) must be implemented under the directory: data/cache/users.

Cache Requirements

The cache should store information for:

• All users present in the route data.
• Any user who presses the Take It button.

Cached user data must be refreshed every 10 minutes via a new Queue command.

The cache will replace the current mechanism for resolving the full user name in existing incidents when Take It is pressed (function fetch_and_assign_user_name()).

At startup, IMPulse must not request user details information (function _generate_users()).

Directory Structure (e.g.)

data/
└ cache/
    └ users/
        <user_id>.json

User fields we should store:

• update_at
• username
• email
• first_name
• last_name
• timezone

Config

No changes are required in configuration files or environment variables.
