chore(cleanup): silence test-only warnings (unused fixtures + stray attrs)

Three small leftovers from prior cleanups:

  - **`utils/purl.rs`**: stray `#[cfg(feature = "maven")] #[test]`
    duplicated immediately above the golang test — leftover from
    the maven dead-test removal in commit b7c4cca. Deleted.
  - **`tests/in_process_python_envs.rs`**: helper `git_sha256` +
    its `sha2` / `Sha256` imports went unused after earlier test
    fixture refactors. Removed.
  - **`tests/in_process_remove_repair_lifecycle.rs`**: two
    `after_hash` test-fixture values that the surrounding mocks
    no longer reference. Prefixed with `_` so the reader still
    sees the intended fixture value.
  - **`tests/apply_network.rs`**: a `let mut args = vec![...]; let _ = args;`
    leftover from removing the apply-takes-api-flags path.
    Replaced with just the `argv` build the rest of the function
    actually uses.

Build is now warning-clean under `cargo build --workspace
--all-features --tests`. No behavior change.
