fix(ombi): resolve TV request status, user, and date display (Issue #53)

Ombi's TV API nests all request data (requestedUser, approved, available,
denied, requested, requestedDate) inside childRequests[] sub-objects.
The application previously only inspected top-level properties, causing
TV shows to consistently display 'unknown' status, 'unknown' user, and
no request date.

Changes:
- OmbiRetriever._hydrateRequest(): hydrate requestedUser on each
  childRequests entry and promote requestedDate to top level
- getRequestStatus() (server + client): aggregate status flags from
  childRequests[] when top-level properties are absent
- Client date display: fallback to childRequests[0].requestedDate
- Add 18 unit tests covering childRequests hydration, status
  aggregation, and date promotion

Closes #53
