fix: add missing imports to headless CLI case and extract modules

[gheylen]

Problem

Both lockknife_headless_cli/case.py and lockknife_headless_cli/extract.py use a sys.modules[__name__] injection pattern — they pass themselves as cli to their register() sub-modules, which then call functions via cli.xxx. However, neither module imported the functions those sub-modules call, causing AttributeError at runtime.

Errors before this fix:

AttributeError: module 'lockknife_headless_cli.case' has no attribute 'create_case_workspace'
AttributeError: module 'lockknife_headless_cli.extract' has no attribute 'extract_sms'

This meant lockknife case init, lockknife extract all, and all dependent commands crashed immediately on invocation.

Fix

Added the missing imports to both modules:

case.py — imports from lockknife.core.case, lockknife.core.custody, lockknife.core.output, lockknife.core.serialize, lockknife.modules._case_enrichment_orchestrator, and lockknife_headless_cli._case_cli_helpers that _case_cli_core, _case_cli_queries, and _case_cli_enrichment all call via cli.xxx.

extract.py — imports from lockknife.core.case, lockknife.core.output, and all extraction modules (_browser_extract_chrome, _browser_extract_firefox, call_logs, contacts, location, media, messaging, sms) that _extract_basic, _extract_all, _extract_browser, _extract_messaging, and _extract_misc call via cli.xxx.

Testing

Verified lockknife case init, lockknife case enrich, lockknife extract all, lockknife extract sms, and related commands run without AttributeError after this fix.

Notes

The same pattern exists in apk.py, intel.py, and ai.py — those may need the same treatment if their sub-modules reference functions via cli.xxx.
