Real-time collaboration: Improve disconnect dialog (#75970)

* Show reconnect countdown in "Disconnected" dialog

* Add "Retry now" link on disconnect dialog, expose reconnect through sync private APIs

* Move retry countdown logic into separate hook file

* Sync connection modal: Redesign with error-specific actions

Redesign the sync disconnection modal to follow the standard Modal
pattern with a header title, left-aligned body, and right-aligned
footer buttons — replacing the previous centered splash layout.

- Use Modal `title` prop instead of hidden header with large icon
- Add "Back to {PostType}" button with dynamic post type label
- Add manual "Retry" button alongside auto-retry countdown
- Promote "Copy Post Content" to primary when Retry is hidden
- Add `canRetry` flag to error messages: `authentication-failed`
  hides Retry (permissions can't be resolved by retrying)
- Stabilize useEffect dependencies with primitive values
- Replace hardcoded colors with `@wordpress/base-styles` tokens
- Add unit tests for `getSyncErrorMessages`

* Show "Retrying..." message when a user initiates the action too, tweak retrying display time

* Disable "Retry" clicks during an active retry
