[FE/BE] Implement forgot password

[afazio1]

Description

Users should be able to reset their password if needed.

Implement the frontend and backend for resetting a password.

Forgot Password Flow ->

• User clicks "Forgot Password" on /login
• User enters their email address in the modal
• If email exists in the db and acceptedInvite: true, then
  • generate a ResetCode
  • send an email to the user with the reset code
  • transition to modal where a user can enter their reset code
  • if the code is correct, allow them to enter a new password
  • Hash and save the new password to the user object
• else display an error message

Reset code -> Create a new model called ResetCode

• take reference from this schema: https://github.com/GTBitsOfGood/VolunTrack/blob/dev/server/mongodb/models/ResetCode/index.ts
• Reset codes are randomly generated 6 alphanumeric characters. Look into Node's builtin crypto library for generating random bytes.
• Reset codes should expire after 15 minutes. Implement this by creating a MongoDB TTL index. Reach out to EM if you need help with this. Email -> Configure and set up Brevo Email API. Credentials are in the Bitwarden
• Use this for reference https://developers.brevo.com/docs/send-a-transactional-email#creating-your-api-request-using-brevo-api-clients
• Use an email template from Brevo. You can create a template on the website using the credentials on the bitwarden
• Update Bitwarden with environment variables like API keys

Other notes

• Take reference from the VolunTrack project! https://github.com/GTBitsOfGood/VolunTrack/commit/0ae6b9482f4efbe0e07b09f56b6d8927e3bd3ae1 They use a different mail service, but the flow is similar.
