Currency dropdown + logo on login/topbar via brandLogo closure

- Onboarding + Settings: Forms\Components\Select for currency
  (MDL/EUR/USD/RON/UAH/RUB) instead of TextInput
- TenantPanel: brandName/brandLogo/favicon as closures resolving from
  tenant. Logo now visible on login page, topbar, sidebar (Filament
  v5 brandLogo handles all 3 spots automatically)
- Favicon falls back to logo if favicon not separately uploaded
- Removed manual SIDEBAR_LOGO_BEFORE injection (replaced by brandLogo)
- Removed manual <link rel=icon> in HEAD_END (replaced by ->favicon)
