Remove array indexes as keys in JSX list components

[kasya]

Replace array index usage in key props with stable, unique identifiers for all list components.

Rule: typescript:S6479
Here's a full list of issues we have under this rule.

Why?

• Performance issues: Array indexes cause unnecessary DOM recreation when item order changes
• State bugs: Component state can become mismatched when items are reordered, added, or removed
• React reconciliation problems: React cannot properly track component identity across renders
• Unpredictable behavior: Leads to subtle bugs that are difficult to debug

Scope

• Replace with stable unique identifiers (IDs, UUIDs, or other unique properties)
• If items lack unique IDs, add them to the data structure

Notes

• May require backend changes to provide unique identifiers

Are you going to work on fixing this?

• Yes
• No
