test: regression tests for dirty with undefined (#5034)

[logaretm]

Summary

• Adds regression tests for issue meta.dirty never becomes true when a field is initialized with undefined #5034 where meta.dirty never becomes true when a field is initialized with undefined
• The underlying bug was already fixed via the normalizeObject function in isEqual which strips undefined values before comparison
• Tests cover: dirty becoming true on value change, dirty resetting on form reset, and isEqual correctly detecting inequality between undefined and string values

Test plan

• useForm.spec.ts: verify meta.dirty becomes true when a field initialized with undefined is changed to 'hello'
• useForm.spec.ts: verify meta.dirty returns to false after resetForm() on a field initialized with undefined
• assertions.spec.ts: verify isEqual({ test: undefined }, { test: 'hello' }) returns false
• All 55 tests pass locally

Pull request overview

Adds regression coverage for #5034 in vee-validate, ensuring meta.dirty correctly flips to true when a field starts as undefined, and validating that isEqual treats { x: undefined } vs { x: '...' } as unequal.

Changes:

• Add isEqual regression assertions for undefined → string transitions in objects.
• Add useForm regression tests verifying meta.dirty becomes true after changing an undefined-initialized field.
• Add useForm regression tests verifying meta.dirty resets to false after resetForm().

[Copilot]

The rest of this spec types form as FormContext (often FormContext<any>). Using Record<string, any> here loses type safety and is inconsistent with the surrounding tests; consider switching to FormContext<any> (or a narrow generic for { test?: string }) for consistency.

[Copilot]

Same as above: form is typed as Record<string, any> here, but other tests in this file use FormContext. Typing it as FormContext<any> (or a narrow generic) will keep the test consistent and avoid accidental misuse of the API.
