### What?
This PR introduces support for copy + pasting complex fields such as
Arrays and Blocks. These changes introduce a new `ClipboardAction`
component that houses logic for copy + pasting to and from the clipboard
to supported fields. I've scoped this PR to include only Blocks &
Arrays, however the structure of the components introduced lend
themselves to be easily extended to other field types. I've limited the
scope because there may be design & functional blockers that make it
unclear how to add actions to particular fields.

Supported fields:
- Arrays
([Demo](https://github.com/user-attachments/assets/523916f6-77d0-43e2-9a11-a6a9d8c1b71c))
- Array Rows
([Demo](https://github.com/user-attachments/assets/0cd01a1f-3e5e-4fea-ac83-8c0bba8d1aac))
- Blocks
([Demo](https://github.com/user-attachments/assets/4c55ac2b-55f4-4793-9b53-309b2e090dd9))
- Block Rows
([Demo](https://github.com/user-attachments/assets/1b4d2bea-981a-485b-a6c4-c59a77a50567))

Fields that may be supported in the future with minimal effort by
adopting the changes introduced here:
- Tabs
- Groups
- Collapsible
- Relationships

This PR also encompasses e2e tests that check both field and row-level
copy/pasting.

### Why?
To make it simpler and faster to copy complex fields over between
documents and rows within those docs.

### How?
Introduces a new `ClipboardAction` component with helper utilities to
aid in copy/pasting and validating field data.

Addresses #2977 & #10703

Notes:
- There seems to be an issue with Blocks & Arrays that contain RichText
fields where the RichText field dissappears from the dom upon replacing
form state. These fields are resurfaced after either saving the data or
dragging/dropping the row containing them.
- Copying a Row and then pasting it at the field-level will overwrite
the field to include only that one row. This is intended however can be
changed if requested.
- Clipboard permissions are required to use this feature. [See Clipboard
API caniuse](https://caniuse.com/async-clipboard).

#### TODO
- [x] ~~I forgot BlockReferences~~
- [x] ~~Fix tests failing due to new buttons causing locator conflicts~~
- [x] ~~Ensure deeply nested structures work~~
- [x] ~~Add missing translations~~
- [x] ~~Implement local storage instead of clipboard api~~
- [x] ~~Improve tests~~
