feat: forgot password flow, member page fixes, country name display

Password reset:
- /forgot-password page: enter email, receive reset link via email
- /reset-password?token=xxx page: set new password with validation
- user.requestPasswordReset: generates token, sends styled email
- user.resetPassword: validates token, hashes new password
- Does NOT trigger re-onboarding — only resets the password
- 30-minute token expiry, cleared after use
- Added passwordResetToken/passwordResetExpiresAt to User model

Member detail page fixes:
- Hide "Expertise & Capacity" card for applicants/audience roles
- Show country names with flag emojis instead of raw ISO codes
- Login "Forgot password?" now links to /forgot-password page

Project detail page:
- Team member details show full country names with flags
