Pull request overview

Implements the first backend slice of password reset by introducing a public password-reset-request endpoint backed by Supabase Auth, and wiring the front-end service to call it while preventing email enumeration via always-200 behavior.

Changes:

• Added POST /user/request-password-reset API operation + shared request model (PasswordResetNetworkRequest)
• Implemented backend flow (UserController → UserService → UserDatastore/Supabase) that suppresses failures and returns success
• Added unit tests for UserService.requestPasswordReset and integration tests for SupabaseUserDatastore.requestPasswordReset
