fifa17-recon: decouple contract suite from the Python implementation

test_fut_contract.py no longer imports ACCOUNT from fut_account. The expected
persona comes from FUT_TEST_PERSONA_ID and the target from FUT_TEST_BASE, so the
suite now imports nothing but stdlib and talks to a server at a URL.

That is what lets these 380 checks certify ANY implementation of the reversed
spec, a future Rust openfut-core included, without replaying the reverse
engineering. The original reason for reading ACCOUNT still holds and is preserved
in the comment: suite and server must not each hold a private copy of the
constant, or the identity-consistency checks would only prove two copies matched.

Also adds pileSizeClientData(0x227) behind FUT_PILESIZES (default off). A probe
run with 16 uniquely-valued entries did NOT move the MY CLUB counter, so that
member is eliminated as its source; the code is kept for the record and flagged
off.

Docs: OPENFUT_PROJECT_REPORT.md and OPENFUT_HANDOFF.md. The report now separates
"built but untested" from "never requested by the client" -- the server log records
User-Agent, and splitting real client traffic (ProtoHttp) from this project's own
probes shows /season, /tournament, /champion, /match, /clubUser and /user/list are
at ZERO client requests. /clubUser (0 client, 93 probe) and /user/list (0 client,
180 probe) are the starkest: work was done on both assuming the client wanted them.

+# LIVE EVIDENCE (2026-08-04): the user opened MY CLUB, the client fetched GET /club

+# counter is NOT derived from the item list; it is a PILE SIZE, delivered
+# separately. massinfo's pileSizeClientData(0x227) is that member and we have never
+# sent it. Parser 0x18013adb0: {"entries":[{"key":<int>,"value":<int>}]} -- key and
+# value BOTH read with the int getter 0x1801c79d0, and the parser IS skip-safe.

+#     recognisable value (100+key). Whatever number MY CLUB then displays names the
