Update test email domain in Bruno API collection files:
- Login User.yml
- Register User.yml
- Update Profile.yml
Ensures API tests use the dedicated test domain and won't conflict
with real user data when developers run tests.
- Move all files from bruno-yaml/* to bruno/*
- Maintains existing directory structure within categories
- Updates bruno/user/auth files with OAuth2 refresh token flow
- Updates bruno/user/profile files for user profile management
- Adds bruno/dashboard/ directory with dashboard API tests
- Preserves all existing test scenarios and OpenCollection YAML format
- No functional changes - file reorganization only
