📝 Walkthrough

Walkthrough

This PR adds a periodic worker task that deletes expired JWT tokens. It introduces env/YAML configuration and worker config structs for interval and max-age, adds a repository Cleanup method to remove expired token rows, implements a periodic cleanup task, and wires the config, repo, and task into the Fx modules.

Changes

Token Cleanup Worker Task

Layer / File(s)	Summary
Configuration Schema and Examples .env.example, configs/config.example.yml, internal/worker/config/config.go	Adds TASKS__TOKENS_CLEANUP__INTERVAL and TASKS__TOKENS_CLEANUP__MAX_AGE examples, tasks.tokens_cleanup YAML, a TokensCleanup config struct and field on Tasks, and default interval/max_age values.
Config Dependency Injection internal/worker/config/module.go	Worker config module provides tokens.Config by converting cfg.Tasks.TokensCleanup interval and max-age to time.Duration.
Token Repository Cleanup Method internal/sms-gateway/jwt/repository.go	Adds Cleanup(ctx, before) to delete tokenModel rows with expires_at < before and return the deleted row count.
Token Cleanup Task Definition internal/worker/tasks/tokens/config.go, internal/worker/tasks/tokens/cleanup.go	Defines CleanupConfig with Interval and MaxAge. Implements cleanupTask as executor.PeriodicTask that computes cutoff (now - MaxAge), calls repository Cleanup, wraps errors, and logs non-zero cleaned row counts.
Token Cleanup Task Wiring internal/worker/tasks/tokens/module.go, internal/worker/tasks/module.go	Adds tokens Fx module: named logger, provides CleanupConfig, registers JWT repository and cleanup task via executor.AsWorkerTask(), and registers tokens.Module() in the tasks module.
