Fixes #1598

validate_journal_file in world_doctor.rs now agrees with the code that actually opens a journal:

• Version range is JOURNAL_VERSION..=MAX_JOURNAL_VERSION (1..=2), matching WorldCore::restore (world/core.rs) — version 0 is refused instead of reported as a valid "format version 0".
• First-entry checks (Created must be first; first entry must be Created) use the count of parsed entries, not the raw split-line index, which blank lines skewed: a leading blank line no longer fails a valid journal and no longer lets a headerless journal pass. (read_journal_entries in world_store.rs skips blank lines before parsing, so restore judges the first parsed entry.) Malformed-entry errors keep the raw line number.

New unit test a_journal_version_zero_and_blank_lines_match_restore pins all three cases from #1598 (version 0, blank-line + Created, blank-line + headerless).

Verification: probe crate on the laptop pre-fix showed doctor/restore divergence on all three cases (see #1598); cargo test --lib world_doctor on the laptop after the fix — results in the closing note on #1598.
