feat: starter code cleanup draft

[Danie1T]

Just a draft PR for now. A bit messy but wanted a review to see if there are any glaring issues.

Tested notification APIs with these changes and the db flow seems ok.

also frontend docker has issues, just testing backend and db with this pr

Some functions in the kept starter code implementations, authService, emailService, fileStorageService, and userService seem to rely on Sequelize to use data from Sequelize tables (Ex: userService finding users by an identifier in Sequelize table). May need to adjust Prisma Schema so that the Prisma tables can hold this data and change functions to work with data in Prisma tables instead.

Would be beneficial to get a greater scope of which of these services rely on Sequelize and make adjustments so that there are none of these instances.

Yes, it will be a good idea to refactor those services to use Prisma instead of Sequelize. At the end of the ticket, there optimally should be now references to sequelize in thte code at all.
