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

[BitHighlander]

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 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, separately catalogued and capturing 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, each with a line saying why it is empty and where the screen actually lives — an empty list already means something in this catalog, 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.
