Fix product list crash with orphaned sales channel references

[moktamd]

Fixes #14945

Summary

What — Filters out null/orphaned sales channel entries in the product list table and product detail views.

Why — When a sales channel is deleted without cleaning up the product-to-sales-channel join table, the API returns null entries in product.sales_channels. The dashboard crashes with TypeError: Cannot read properties of null (reading 'name') when rendering these entries.

How — Replaced unguarded .map() calls with a type-safe filter predicate that narrows (SalesChannelDTO | null)[] to SalesChannelDTO[] before accessing .name or .id. Applied in both SalesChannelsCell (product list table) and ProductSalesChannelSection (product detail page).

Testing — To reproduce:

1. Create a product and assign it to a sales channel
2. Delete the sales channel directly from the database (or via API) without removing the join-table entry
3. Navigate to the product list — the page crashes
4. With this fix, the product list renders normally, skipping the orphaned channel references. Tooltip counts and "available in X of Y" text reflect only valid channels.

Thank you for your contribution!

After reviewing this PR, we need a few things addressed before we can move forward:

Required changes:

• Add a changeset — run yarn changeset and select @medusajs/dashboard as a patch. The message must follow the format: fix(@medusajs/dashboard): short description
• Fill in the PR description using our pull request template. The Testing section is missing — please describe how the reviewer can reproduce the crash and verify the fix (e.g., steps to create an orphaned sales channel reference and confirm the product list no longer crashes).

Notes:

• filter(Boolean) is not a type-safe predicate in TypeScript — it won't narrow (SalesChannelDTO | null)[] to SalesChannelDTO[]. If you're adding null-filtering, consider a type guard instead:

.filter((sc): sc is SalesChannelDTO => sc !== null && sc !== undefined)

This ensures downstream .name accesses are type-safe after filtering.

• The fix correctly addresses the UI crash, but the root cause is that the API returns null elements in product.sales_channels for orphaned join-table rows. It may be worth a follow-up issue on the backend side.
