🪟 🎉 Disable deselection of cursor field/primary key in the UI

[josephkmh]

What

Closes #20586

This PR automatically adds special handling of cursor fields and primary keys with regards to field selection in the airbyte UI.

How

• Disables the deselection of the primary key(s) or cursor field, instead displaying a tooltip with an explanation
• In case a user selects a cursor or primary key that was previously deselected, the UI automatically selects this field
• Extracts logic from useCallback() functions into pure functions, adds unit tests to cover these

Recommended reading order

1. FieldRow.tsx - where the pk & cursor field deselection is disabled
2. CatalogSection.tsx - where useCallback() logic has been extracted to pure functions
3. streamConfigHelpers - the pure functions that return a new stream config

Haven't found why in the code yet, but it doesn't look like this takes into account source-defined cursors and primary keys.

(^ this example is from a Mailchimp source. The disabled rows are part of my composite primary key that I configured, but my cursor (timestamp) can still be toggled.)

[teallarson]

Code lgtm and tested locally.

I think it would be prudent to add a test case specifically for source-defined cursors and source-defined primary keys not being able to be deselected, but I don't necessarily think it's blocking.

This converts the fieldPath (e.g. ['path', 'to', 'field']) into a string (e.g. "[\"path\",\"to\",\"field\"]") so that we can add it as a unique value to the set. It gets converted back into an array before returning.

This conversion between String[] > String > String[] might seem expensive, but it allows us use a Set to avoid duplicates when merging, which avoids a lot of nested comparisons of arrays.

I think that's a reasonable tradeoff. It sounds like it would still be more efficient for a large sync catalog or a sync catalog with a lot of changes than what this was doing before, correct?

[josephkmh]

Yes, at least as efficient, and in the best case more efficient 👍

Thanks @tealjulia! I made one more minor adjustment here FYI d193819
