Empty States Missing and Improper Error Handling on PO Review Detail Page

[Adameddy26]

Current behavior

Missing Empty State - PO Items:
When all uploaded CSV PO items are missing, the page does not display any feedback or empty state message, leaving the user unaware of what went wrong.

Missing Empty State - Facilities Modal:
The modal remains blank when all facilities are properly linked, providing no confirmation or feedback to the user.

Improper Error Handling:
Despite errors like:
Date-time parsing issues
Missing products
Missing facilities
The app allows the file upload, creates a record in OMS, and marks the status as Finished, misleading the user into believing the file was processed successfully.

Mapping Chip State Issue:
When a mapping chip is selected, and the user discards changes or uploads a new file, the chip incorrectly remains pre-selected and disabled, causing confusion during subsequent actions.

Expected behavior

Empty States:
Display appropriate empty state messages for

1. Missing PO items on the PO Review Detail Page.
2. Missing Facilities Modal when all items are linked.

Error Handling:
Notify the user of specific issues (e.g., date-time parse errors, missing products, missing facilities).
Clearly indicate that problematic items will not be processed, but valid ones will proceed successfully.

Mapping Chip State:
Reset the chip state when the user discards changes or uploads a new file.

Steps to reproduce the issue

Case 1
Upload a CSV file with POs where some items are missing or contain errors (e.g., date-time parse issues, missing products/facilities).
Navigate to the PO Review Detail Page:
Observe the absence of an empty state when no items are present.

Case 2
Upload a CSV file with POs having correct data.
Open the Missing Facilities Modal:
Observe the absence of an empty state when all items are linked properly.

Case 3
Upload a CSV file with POs where some items are missing or contain errors (e.g., date-time parse issues, missing products/facilities).
Upload the file and check OMS:
Note that the file upload is marked Finished, despite errors.

Case 4
Upload a CSV file with POs having correct data.
Select a mapping chip, discard changes, and upload a new file:
Observe the mapping chip's persistent pre-selection.
