feat: Remove unused 'finalizing' phase from indexing progress

Eliminates the intermediate 'finalizing' phase that was added as a progress bar transition state but served no functional purpose. Simplifies the progress flow by going directly from 'storing' to 'resolving' phases, removing associated UI labels and progress callbacks.
