adhoc: Fix Clippy lints in const-serialize etc. (#3880)

* adhox: Fix Clippy lints in const-serialize etc.

Fix the clippy lints that were preventing building:

   * const-serialize/src/lib.rs
   * core/src/nodes.rs
   * fullstack/src/serve_config.rs

* adhoc: Change the way to satisfy the lint for 1.85

The lint for pointer comparison is only in 1.85. The solution
uses a mechanism that was only stabilized with 1.85. Instead
of using that solution, will just allow the lint on this
function for now. Once the MSRV of Dioxus is updated to 1.85
or above, this can be changed to use the recommeneded solution.

* adhoc: Fix the 'cargo make test' tests

There were a number of tests failing to compile and/or run.
Fixed those that could be meaningfully fixed. Those that were
incomplete examples that could not be fixed are marked as
'ignore'.

* adhoc: GitIgnore test results in playwright tests

* fix wry rollback
