Match the Company Settings design pattern: sidebar navigation on desktop
with dropdown on mobile, child routes rendered via RouterView. Each tab
(General, Profile Photo, Security) is now a BaseSettingCard with its own
route under /admin/user-settings/{general,profile-photo,security}.
Backend:
- Extract user profile methods (show, update, uploadAvatar) from
CompanyController into new UserProfileController
- CompanyController now only handles company concerns (updateCompany,
uploadCompanyLogo)
- Remove Account Settings from setting_menu config
Frontend:
- New /admin/user-settings page with 3 tabs: General, Profile Photo,
Security (password change)
- User dropdown now links to /admin/user-settings instead of
/admin/settings/account-settings
- Settings sidebar defaults to Company Information as first item
- Remove old monolithic AccountSetting.vue
