Alexey MilovidovandClaude Opus 4.5 62ccfbd3aa Improve help output for ClickHouse applications ...

This commit improves the help output for all ClickHouse applications:

- Add `clickhouse help` command that lists all available subcommands
- Return exit code 0 for all help messages (previously some returned 1)
- Output help messages to stdout instead of stderr
- Use "clickhouse <cmd>" format instead of argv[0] in help messages
- Add dynamic `app_name` detection for `clickhouse client` and `clickhouse local`
  to show correct invocation name based on how the binary was called
- Add `--no-sudo` option for `clickhouse start` and `clickhouse restart`
  for environments without sudo (e.g., Docker containers)
- Add detailed help headers and footers for client and local with usage examples

Closes #58244
