feat(validation): make hostname validation case-insensitive and expand allowed characters

- Normalize hostnames to lowercase for RFC 1123 compliance while accepting uppercase input
- Expand NAME_PATTERN to allow parentheses, hash, comma, colon, and plus characters
- Add fallback to random name generation when application name doesn't meet minimum requirements
- Add comprehensive test coverage for validation patterns and edge cases
