release(v1.7.1-alpha): version bump for end-to-end OTA test

Trivial bump on top of df83163f. No code changes — this exists purely so
the fleet nodes now sitting on 1.7.0-alpha have a real target to exercise
the OTA pipeline against: check → download → apply → restart → state
reconciliation. The binary content differs only in the embedded
CARGO_PKG_VERSION string.

Frontend tarball reused from v1.7.0-alpha (same bytes, copied to a new
filename to match the manifest component name convention).

Artefacts:
  archipelago                                     7f7981bd…56eef0  40391760
  archipelago-frontend-1.7.1-alpha.tar.gz (dup of 1.7.0)  dc3b63af…e9a8370  76984288

Manifest changelog is a single plain-language sentence explaining that
this is the test release — per the saved feedback about keeping
fleet-facing strings readable.

+    "Over-the-air update test — same features as 1.7.0, just a fresh version number so your node can try the new download-and-apply flow end-to-end. Safe to apply; nothing to do afterwards."
