String literals in benilla-assets, -blp, -protocol and -srp carry no record numbers (#291)

Part of #92, for the crates whose comment pass has landed and whose literals are few: `benilla-assets`, `benilla-blp`, `benilla-protocol` and `benilla-srp`.

- Assert messages, printed labels and a probe's error text drop their private record and bug numbers and the workspace's name for the maintainer. Each keeps its fact in its own words. One assert names a client function by its address, `0x68a830`, instead of a disassembler's label for it.
- Two terrain tests named after a bug number are renamed for what they check: `the_pin_stands_one_chunk_west_of_an_impassable_band` in `benilla-formats`, and `a_body_walking_east_from_the_pin_is_stopped_at_the_wall` in `benilla-world`. Those two crates' other literals follow in their own pass.
- Every change is to string-literal text, proven with comments stripped and every literal masked, except the two renamed tests.
