Remove unused URL encoding functionality and update dependencies

- Removed "urlencoding" from .cspell.json as it is no longer needed.
- Added new dependencies in Cargo.lock including "displaydoc", "form_urlencoded", and "url".
- Updated the Cargo.toml to include the "url" dependency.
- Refactored ipc_http_server.rs to utilize the "url" crate for query parameter parsing instead of the removed "urlencoding" module.
- Cleaned up the RequestContext structure to include path parameters.
- Removed the test for URL decoding security from lib.rs as it is no longer applicable.
