fix(wallet): redeem across all federations, unified ecash history, fmcd healthcheck

- reissue_into_any now tries the UNION of the local registry AND fmcd's live
  joined set (/v2/admin/info) before failing, so a valid Fedimint token isn't
  wrongly rejected when the registry has drifted. On all-fail it returns a
  friendly message: notes already redeemed into this wallet (funds safe) vs
  didn't match any connected federation.
- Unified transaction history: a local Fedimint tx log (recorded on each
  successful redeem) is merged with the Cashu history in wallet.ecash-history,
  newest-first, each tagged kind=cashu|fedimint. Previously a Fedimint receive
  appeared nowhere.
- fedimint-clientd healthcheck -> type:tcp. It was probing /health, which fmcd
  doesn't serve (only /v2/*), pinning the container in (starting) forever; the
  TCP probe is skipped by the Quadlet renderer (host-side lifecycle verifies),
  so it reports running. Cosmetic for ecash, which worked throughout.
