Add conditional clawback details on show page

[dp-daly]

Context

We are making progressive enhancements to the support console to assist in the processing of Claims.

Changes proposed in this pull request

• Add the Clawback details to the clawbacks show page (an initial show page was added in dpd/request-clawback-wizard)
• Use change links on 'number of hours' and 'reason for clawback' which link to the edit request clawback wizard. This section should only be visible if a clawback has been requested.
• If the clawback is in progress the Clawback details should be visible, but the change links should not be available.

Guidance to review

• Navigate to the show page of claims with all three clawback statuses (sampling_not_approved, clawback_requested, and clawback_in_progress.
• Check them against the logic outlined above.
• Note that the values for clawback hours and reason are not yet in place. Changes to the Claims table have been postponed until a further design iteration has been approved and handed over.
