feat: add /accounts and /logout commands

Commands Added:
- /accounts: Opens account management window showing all accounts
- /logout: Removes the active account
- /logout --all: Removes all accounts

Components Created:
1. AccountManager (src/components/AccountManager.tsx)
   - Lists all accounts with avatars, names, and public keys
   - Shows active account with checkmark indicator
   - Switch account button for inactive accounts
   - Remove account button with confirmation dialog
   - Add account button that opens command launcher
   - Empty state with helpful instructions

2. LogoutHandler (src/components/LogoutHandler.tsx)
   - Handles logout and logout-all actions
   - Shows confirmation dialog for logout-all
   - Displays toast notifications for success/error
   - Auto-closes after execution

Type System Updates:
- Added "account-manager" and "logout-handler" to AppId type
- Integrated both components with WindowRenderer routing

Man Pages:
- Added comprehensive documentation for both commands
- Includes usage examples and related commands
- Proper categorization as System commands
