feat(setup): "Claim this frame" checkbox for previously-bound MACs
CI / test (push) Has been cancelled
Details

Browse Source 
Use case: old owner sells the device to a friend. Friend holds the BOOT
button to wipe NVS, joins the device's AP, sets new WiFi. The old
owner's account is still bound to the MAC server-side, so without
explicit consent the friend would silently take over (or, worse, the
old owner's photos would keep displaying until claim).

Flow now:
  - GET /setup/{mac} detects MAC bound to anyone and renders a
    "Claim this frame as my own" checkbox + a banner explaining what
    the takeover wipes. Both register and login panels carry the
    checkbox; submitting either form without it bounces back through
    the index with a session-flashed error.
  - DeviceService::linkToUser now requires allowClaim=true to
    transfer ownership. Without it, throws DeviceClaimRequiredException
    that the controller catches and turns into the bounce-with-error.
  - On a successful claim, the takeover wipes:
      * old image-device approvals
      * device_image_history rows for the device
      * name, wakeTimes, currentImage*, lockedImage, nextPollExpectedAt
    so the new owner starts from a fresh slate, not inheriting the
    seller's "Living Room / 4:30 AM" preset.
  - Already-logged-in user visiting /setup/{mac} for someone else's
    device falls through to the form (instead of silently transferring
    on page load) so the checkbox is the only path.

Test matrix:
  - SetupControllerTest: 5 new functional cases — checkbox renders for
    bound MACs, register/login without checkbox bounce + retain old
    ownership, register WITH checkbox transfers + purges, logged-in
    other-user falls through to form.
  - DeviceServiceTest: 3 new unit cases — throw without consent,
    isClaimedByAnotherUser true/false matrix, takeover resets device
    state.

Coverage: 99.70% lines / 98.19% methods backend, 333 frontend tests
green via ddev tests.
