Add logs view for timer functions

- Create new database table `timer_function_invocations` to track function executions
- Implement `/logs/<function_id>` route in timer routes to fetch and display invocation logs
- Add new logs template for timer functions with detailed invocation information
- Update header templates to include logs URL for timer functions
