Issue 1: Inconsistent App Names

[PrinceSajjadHussain]

Body:
The Spark application name is not consistent across all Spark jobs. monthly_user_site_hits_job.py and players_scd_job.py use "players_scd," while team_vertex_job.py also uses "players_scd". This can lead to confusion when monitoring or debugging Spark applications. The application name in team_vertex_job.py should be updated to reflect the job it's running, for example, "team_vertex".
