test: repair pre-existing flakes in cli_flags, fingerprint iter, submodule

Three unrelated test issues were masking the fingerprint regression
above and need to be green for the suite to be trustworthy:

1. tests/test_cli_flags.py: 7 tests monkeypatched input() to return "5",
   but in the no-hashfile main menu "5" enters the Wordlist Tools
   submenu and then loops forever on "Split by Length" / "File not
   found". Changed to "7" (Exit), the documented exit option.

2. tests/test_fingerprint_expander_and_hybrid.py: the iter-based
   lineCount mock (iter([1,1,1])) raised StopIteration because
   _run_hcat_cmd now also calls lineCount once per invocation when
   notifications fire. Replaced with a constant `lambda _p: 1` so the
   test no longer couples to internal call counts.

3. tests/test_submodule_hashcat_utils.py: `git submodule update --init`
   exits 0 in git worktrees but does not populate submodule
   directories. The test failed environmentally for anyone running it
   from a worktree. After the init attempt, if the dir is still empty,
   pytest.skip with a clear message rather than fail - preserves the
   original intent for normal checkouts.
