Gift claim: name the real failure when the funding tx isn't visible

Claiming a gift whose funding tx is unknown to the claimer's data
source (different network/chain, or not yet propagated) used to fail
with the misleading "already been claimed". Now:
- the claim screen probes the funding tx up front (esplora's status/
  outspend endpoints don't 404 for unknown txids, so outspend alone
  can't detect this) and shows a network/data-source notice, and
- a missing-inputs broadcast rejection maps to the same explanation
  instead of the generic already-claimed message.
