Fix: uncontrolled input in dashboard

[Animesh404]

What kind of change does this PR introduce?

a Bugfix for #889

Summary

• Removed checked property: This avoids conflicting control by letting getInputProps fully manage the checkbox state.
• Added defaultSettings which provides default values for all fields, preventing uncontrolled-to-controlled issues.

This looks like the third place we are duplicating configuration setting names. Is there any way to populate this dynmamically?

[Animesh404]

we populate this dynamically using config file but sometimes we might get undefined values which might be the reason for warning. So, I added these default values

[abrichr]

Won't this prevent the checkboxes from being checked appropriately depending on the configuration values?

[Animesh404]

...form.getInputProps('RECORD_WINDOW_DATA') this alone should've marked this checked but yes now that I tested it again without checked= property it is not being marked appropriately.
