[4.x] Arguments resolution issue in testing

[dmason30]

Description

Dan Harrin requested this PR to show a failing test. It demonstrates a regression where assertActionExists() and assertActionVisible() fail to pass provided arguments to an action before its schema is resolved.

In Filament v4, when an action is defined with a record() closure that depends on $arguments, and that record is subsequently used within a schema() closure, testing assertions throw an ErrorException: Undefined array key because the arguments are not yet merged into the action instance during the assertion's resolution phase.

ErrorException: Undefined array key "post_id"
