Social: Integrate post list share action with the unified modal

[manzoorwanijk]

We allow users to click on the "Share" link from the post list screen which redirects to the editor with resharing modal open.

We need to update that logic to make it work with the unified modal via the feature flag.

Related to #46323

Closes SOCIAL-277

Proposed changes:

• Update handleSharePostAction to open the unified modal when the UNIFIED_UI_V1 feature is enabled, otherwise fallback to the original share post modal.

Works well with the feature flag, and also compatible with sites not having it
