✨ feat(token): auto-generate default token names when user input is empty

When creating tokens, if the user doesn't provide a token name (empty or whitespace-only),
the system will now automatically generate a name using the format "default-xxxxxx" where
"xxxxxx" is a 6-character random alphanumeric string.

This enhancement ensures that all created tokens have meaningful names and improves the
user experience by removing the requirement to manually input token names for quick token
creation scenarios.

Changes:
- Modified token creation logic to detect empty token names
- Added automatic fallback to "default" base name when user input is missing
- Maintained existing behavior for multiple token creation with random suffixes
- Ensured consistent naming pattern across single and batch token creation
