fix: update customize fields navigation to go directly to object detail page (#12904)

## Summary
- Updates "Customize fields" button navigation to go directly to the
specific object's detail page
- Changes navigation from `SettingsPath.Objects` to
`SettingsPath.ObjectDetail`
- Aligns with existing behavior of "Edit Fields" functionality

## Problem
When clicking "Customize fields" in the record table header plus button
dropdown, users were taken to the general objects list page instead of
the specific object's fields page, making it harder to find and
customize the relevant object.

## Solution
Changed the navigation path from `SettingsPath.Objects` to
`SettingsPath.ObjectDetail` in `RecordTableHeaderPlusButtonContent.tsx`,
which takes users directly to the object-specific fields page where they
can see and manage all fields for that object.

## Screenshots

### Before: Customize Fields Dropdown
When clicking the "+" button in the table header, the dropdown shows
"Customize fields" option:

### After: Direct Navigation to Object Fields
Clicking "Customize fields" now navigates directly to the specific
object's fields page:

\![Companies Object Detail
Page](https://github.com/user-attachments/assets/companies-object-detail-page-fixed.png)

## Test plan
- [x] Navigate to any record table view (e.g., People, Companies)  
- [x] Click the "+" button in the table header
- [x] Click "Customize fields"
- [x] Verify navigation goes directly to that object's fields page
instead of the general objects list
- [x] Confirmed the URL is `/settings/objects/{objectNamePlural}` (e.g.,
`/settings/objects/companies`)
