Backend: https://github.com/quiltdata/enterprise/pull/779

Also, some refactoring and fixing minor bugs:

• SelectionItem { logicalKey: string } type instead of a string
• Better aligning (fixing MUI bug)
• Re-use components

• Changelog entry (skip if change is not significant to end users, e.g. docs only)

looks reasonable

Used React.Provider for passing selection data instead of props. It was required to use utils/Dialog, because it is initialized in callback and doesn't react to props changes.

Also, fixed route guarding: confirming navigation from package page when something is selected. The condition turned out to be quite sprawling: https://github.com/quiltdata/quilt/pull/4173/files#diff-95c902495a06ff31c5e3a2bede51af727048f9151bede5b5195a4f2cb8fc5090R106
