fix(report): stop declaring screens seven tests cannot draw

The report's own gate was failing:

    screenshot audit FAILED -- declared screens with no capture:
      test_msg_ethereum_getaddress::test_ethereum_getaddress
      test_msg_ripple_get_address::test_ripple_get_address
      test_msg_ethereum_clear_signing::test_valid_metadata_returns_verified
      test_msg_solana_getaddress::test_solana_get_address
      test_msg_tron_getaddress::test_tron_get_address
      test_msg_ton_getaddress::test_ton_get_address
      test_msg_zcash_orchard::test_fvk_reference_vectors

None of them is a missing capture. Each entry declared a screen the test can
never produce:

  - the five *getaddress* tests return the address ON THE WIRE. The drawn
    address is the *show_address* sibling, which is separately catalogued and
    does capture it (S3b, T3b, N2b, B4).
  - test_valid_metadata_returns_verified asserts the VERIFIED classification
    before anything is rendered.
  - test_fvk_reference_vectors is reference-vector arithmetic compared in
    memory.

So the declarations were wrong, not the runs. Emptied, and each carries a line
saying why it is empty and where the screen actually lives -- an empty list is
already meaningful in this catalog ("refusal paths draw nothing, and their
evidence is the Failure on the wire plus the ABSENCE of a ButtonRequest"), so
it must read as intent rather than omission.

This matters beyond tidiness. The audit is a release gate, and a gate that
fails for a reason nobody can fix gets ignored -- and an ignored gate is the
one that misses the real defect later. It now passes:

    screenshot audit: every declared screen was captured
