Fix job seeker document submission: hide raw storage URL, fix error masking

Two issues in the job seeker (and shared profile) dashboard:
- The uploaded document's full Backblaze URL was rendered as visible text
  and linked directly; view-document now resolves a short-lived signed
  URL on demand instead of exposing the permanent storage link.
- "Submit for Verification" always showed a generic "Network error"
  message on any failure because request() throws on non-2xx responses,
  making the destructured status/data unreachable in the catch-free path
  (e.g. a 409 "verification already in progress" looked identical to a
  network failure). Now surfaces the real backend error message.
