add membership dashboard functionality and some of renewal flow

[dniael]

• fully implement membership dashboard functions
• renewal flow on frontend should be done
• • i added a new shared sql query called "update_individual_application" in supabase. Currently, the supabase function called via RPC from the codebase is "create_individual_application". "update_individual_application" has the same functionality as "create_individual_application", except it is able to update a current application if it exists already.
• • as of right now i have not run the query so the new "update_individual_application" function has not been created.
• • • ISSUES:
• • • • keep or delete old application reviews?
• • • • able to edit the function body for the original "create_individual_application" function so that we dont have to do 2 rpc calls in the code?
• • • • able to add new .sql migration file in the codebase based on the changes to "create_individual_application"?
