Passed variables to the time_tag template [time_tag.html] that checks if an event was scheduled to start or end with the current year.

More events are created to test particular scenarios of events especially events set to start or end at a future year.

…t Year

The time tag now displays the year when an event will occur. This is only for events that have been scheduled to start or end in at a future year. The accompanying functional tests have also been included.

All test data concerning the provision of data to serve the functional tests have been moved to the functional test.
As it improves readability.
All other test data at test_views.py was reset
to accommodate for the reduction in number of test data instances.

…plemented With Unit Tests

Since the current CI at the main branch does not support selenium [web driver] operations, the functional test which depends on selenium to run has been removed.

- Updated the test methods `test_scheduled_to_start_this_year_method` and `test_scheduled_to_end_this_year_method` to better reflect event scheduling edge cases.
- Added assertions to verify when events are not scheduled to start or end within the current year.
- Utilize `unittest.mock` to clamp down datetime-sensitive tests.
