Shortened the code by 210 lines. Also, removed docstrings because they are not needed for CLI commands (more maintenance burden).
- `_common_http_options`: shared decorator for 10 Click options used by get/post/put/delete (was repeated 4x)
- `_common_browser_options`: shared decorator for 11 Click options used by fetch/stealthy_fetch (was repeated 2x)
- `_data_options`: shared decorator for `--data`/`--json` options used by post/put
- `__http_command()`: shared implementation body for all HTTP commands (was 4 separate `from scrapling.fetchers import Fetcher` + `__Request_and_Save` blocks)
- `__build_browser_kwargs()`: shared kwargs builder for fetch/stealthy_fetch (was duplicated)
