fifa17-python: sync tools to running container state

The frozen baseline image predates two hot-patches made in the running
container after build:
* utas_server.py: FUT_MODES-gated offlineSeason block in GetHubData's club
  response (keeps the offline-season summary valid)
* test_hub_offline_season_contract.py added to /app/tools

Sync fifa17-python/tools to the running container (verified byte-identical,
237 files incl. the redir cert pair) and snapshot the live FS as
openfut-fut-backend:python-running-2026-08-10 (docker commit). A fresh build
from the committed sources now reproduces the running backend exactly
(baked SHA256SUMS.txt diffed against the container manifest: identical).

+CardsDLL's hub parser at 0x180139610 recognizes offlineSeason (atom 0x1ec)
+and passes its object to 0x18013c3a0. That nested parser recognizes the
+string-valued divisionId, gamesPlayed, points, totalGames, and
+progressDataVersion fields. Without offlineSeason, the Single Player Season
+UI rejects the otherwise-successful GetHubData response before /season is sent.
