ChuckBuildsandClaude Sonnet 5 2eea7a7f58 fix(baseball): don't drop favourite MiLB games on the diagnostic path
The competition-level status fallback fixed the inning lookup, but the
favourite-team debug block a few lines above still read the event top-level
game_event["status"]. MiLB events (synthesized from the MLB Stats API into an
ESPN-like shape) populate only the competition-level status, so the identical
event that extracted fine for a non-favourite raised KeyError and returned
None once the team was a favourite.

Worst possible shape for the bug: it only hit the games the user cared most
about, and only on the path meant to help diagnose them. The existing
regression test missed it because it never passes favourites, so
is_favorite_game was False and the block never ran.

Uses the validated competition-level `status`, which
_extract_game_details_common guarantees is present by that point. Adds a
favourites-passing companion test; confirmed it reproduces the KeyError
without the fix.

"""Characterization tests for src/base_classes/sports.py.
These tests PIN the current behavior of SportsCore / SportsUpcoming /
SportsRecent / SportsLive ahead of the sports-unification merge (features
from nine drifted plugin copies are about to be folded in). They assert
what the code DOES today, not what it should do — a few pinned behaviors
look like bugs and are flagged inline with "PINNED AS-IS".
Coverage:
- `_extract_game_details_common` + the four sport extractors
(football/hockey/baseball/basketball) against realistic ESPN scoreboard
events (adapted from the ledmatrix-plugins monorepo test fixtures).
The output must remain a superset of the frozen skin view-model
contract (GUARANTEED_KEYS, imported from test_skin_system).
- update() flow for concrete SportsUpcoming/SportsRecent/SportsLive
subclasses: population, favorite-team filtering, empty/failed-fetch
tolerance. All offline: `_fetch_data` reads a pre-seeded mocked cache
and every instance's requests session raises ConnectionError.
- Rendering smoke: one `display()` per mode class at 128x32 draws
non-zero ink onto a real PIL image.
- Guard rails: the skin-system seam methods on SportsCore must survive
the merge.
