fix(channels): clippy doc_markdown warnings in telegram.rs elicitation test comments

[bug-ops]

Summary

Two clippy::doc_markdown warnings in crates/zeph-channels/src/telegram.rs cause cargo clippy --all-targets --features full --workspace -- -D warnings to fail.

Introduced by PR #2545 / #2548 (elicitation phase 2).

Location

crates/zeph-channels/src/telegram.rs, lines 1051–1052:

/// Verify the timeout branch of elicit() at the rx level, matching the
/// same pattern used in confirm_timeout_logic_denies_on_timeout.

Fix

Wrap identifiers in backticks:

/// Verify the timeout branch of `elicit()` at the rx level, matching the
/// same pattern used in `confirm_timeout_logic_denies_on_timeout`.

Reproduction

cargo clippy --all-targets --features full --workspace -- -D warnings

Expected: zero errors. Actual: 2 doc_markdown errors in zeph-channels, compilation aborted.
