test: fix two stale unit tests failing on main CI

[swati510]

What

Two unit tests have been failing deterministically on main across Python 3.11/3.12/3.13. Both are stale tests, not source regressions — the underlying behavior changes were intentional; the tests just weren't updated alongside them.

1. test_batch_upsert_graph_edges_updates_existing

assert 1.0 == 0.5

PR #807 (fix(graph): keep max confidence on edge upsert) made _update_graph_edge keep max(existing, new) confidence on collision, so a real call can't be stamped below the flow-calls floor by a later lower-confidence upsert. The test still asserted that a lower re-upsert (0.5) overwrites the default (1.0).

Fix: seed the edge at 0.7, re-upsert at 0.5, and assert confidence holds at 0.7 — directly covering the max-keep contract while still verifying the in-place imported_names_json update.

2. test_hedged_but_named_body_served_holds_medium

assert 'low' == 'medium'

PR #796 added repo_root= and session_factory= keyword args to the _anchor_symbol_hits call site. The test's _fake_anchor stub only accepted the four positional args, so the real call raised TypeError — swallowed by the contextlib.suppress(Exception) around it. Anchoring silently no-op'd, _anchor_symbols was never attached, served_named_body stayed False, and the hedged answer fell to low instead of medium.

Fix: the fake now accepts **kwargs so it matches the real signature.

Test

Both files pass locally (55 tests):
