* Fix test suite: ESM loading and stub isolation (refs #605)
Three targeted fixes to reduce suite failures from 9 → 1:
1. package.json: add "type": "module" so Node loads static/js/**
as ES modules. Fixes 7 tests in test_compare_js.py and
test_reply_recipients_js.py that fail with
"SyntaxError: Unexpected token 'export'".
2. test_null_owner_gates.py: add Base and ChatMessage to the
core.database stub. Without Base the scheduler test cannot
import at collection time; without ChatMessage core/__init__.py
fails mid-load when session_manager.py tries to import it,
leaving core partially initialised in sys.modules and poisoning
the auth manager migration test that runs later in the same file.
3. test_task_scheduler_session_delivery.py: skip gracefully when
core.database is stubbed (Base is a MagicMock) rather than
crashing. The test passes correctly when run in isolation.

* Scope ESM declaration to static/js/ and document isolation workaround
Per review feedback on #844:
1. Move "type": "module" from root package.json to static/js/package.json.
The root package.json had no type field (defaulted to CJS) and should
stay that way — vendored UMD bundles in static/lib/ use require() internally
and would break if Node ever tried to load them as ES modules. Node resolves
the nearest package.json, so adding it in static/js/ scopes the ESM
declaration to just the files the JS unit tests actually load
(compare/state.js, emailLibrary/replyRecipients.js).
2. Expand the module-level skip comment in test_task_scheduler_session_delivery
to document that it is a temporary isolation workaround, explain root cause
(test_null_owner_gates installs a module-level sys.modules stub with no
cleanup), record before/after suite numbers, and note the clean path
(refactor to fixture-scoped stub).
