feat(completions): enhance cliproxy help and update shell completion scripts

- Styled cliproxy help output with UI primitives and added status hint
- Added cliproxy --help reference to main help command
- Updated bash, zsh, fish, and PowerShell completions with:
  - Missing commands (api, cliproxy)
  - CLIProxy OAuth profiles (gemini, codex, agy, qwen)
  - Provider flags and update command flags
