2add759f40 fix(odds): identify the odds requests to ESPN (#451)
The odds fetch used a bare requests.get, so it went out as
python-requests/x.y -- the one agent ESPN is known to reject. Around
2026-08-04 it began 403ing browser strings and bare custom tokens alike;
what it accepts is a token carrying a URL that says who is calling.
Every other ESPN caller in the tree already sends that header
(src/common/api_helper.py, src/base_classes/data_sources.py); this path
was simply missed.

It is the worst one to miss. Odds are fetched per live game from inside
the live update loop, so its failures are the ones that cost the caller
its whole update budget -- the same path the 5s timeout and the cooldown
were added to protect.

Sent via a session rather than per-call, which also reuses the
connection across a slate. Deliberately no retry adapter, unlike
api_helper: retries multiply request_timeout, which is 5s precisely to
stay inside the 30s operation budget.

The existing tests patched the module's requests.get, which this change
bypasses -- test_base_odds_manager was consequently reaching the real
ESPN and taking 404s. Both files now patch the session, and the new
tests pin the agent against api_helper's live value so the two cannot
drift apart the next time ESPN moves the goalposts.

"""
Tests for src/base_odds_manager.py (BaseOddsManager).
Covers get_odds validation/caching/URL construction, the null-safe
_extract_espn_data fix (ESPN sends explicit JSON nulls for absent sides),
the no_odds sentinel, stale-cache fallback on request failure,
is_odds_available's ML-blind truth table, the fixed format_odds_summary
gate (money-line-only odds now format), get_odds_for_games, and
configuration loading.
No real network: requests.Session.get is always patched. The odds path sends
its requests through a session so it can identify itself to ESPN, so patching
the module-level requests.get would no longer intercept anything.
