fifa17-recon: match rewards, POW online layer, account backend, quick sell

Browse Source 
Second session. FUT core loop, the EASFC/POW online layer, a central account
backend, and a lot of corrections. Everything risky is behind an env flag with
the default set to whatever was live-proven.

WORKING END TO END (live-verified this session):
  * match loop -- POST/PUT/POST/DELETE ut/%s/match, rewards via FutDestroyMatch
    (0x180121b60). Play a match, get coins, W/D/L updates.
  * packs -- buy, cards land in the club, session survives (FUT_PACK_AUTOCLUB=1)
  * quick sell -- POST ut/delete/%s/item was UNMAPPED and paid NOTHING; six cards
    were destroyed for 0 coins. Now credits discardValue.
  * POW/EASFC online -- the "EA FC servers unreachable" banner is powdll's layer,
    a THIRD http api on :8094 nobody had served. Redirect needs no root: powdll
    FUN_18005a460 reads FIFA_POW_URL from the same client-config store as
    ROSTERUPDATE_URL. FUT_POW=1.
  * account backend -- fut_account.py replaces 7 hardcoded copies of the persona
    across 5 files; club/persona/online-profile editable via CLI.

CORRECTIONS TO ENDPOINT_MAP (all re-extracted from the deserializers):
  * FutStoreGetPackTypes: id/packType/isPremium/quantity/saleType/purchaseLimit/
    purchaseCount are NOT skipped no-ops -- all are parsed. extPrice inner objects
    take externalPriceId(0x11a), not amount/currency.
  * FutMoveCard 0x180128600 has NO skip handler (FUN_180135ff0 appears zero times,
    unique among FUT deserializers) and parses only itemData -> dreamSquads.
  * class -> deserializer resolution: the name literal is preceded by a 4-BYTE
    HEADER and the factory LEA points at the header, so look up name_addr - 4.
    Six attempts failed on this; now ghidra_env.class_deser(). Unlocked 11 SBC/
    Draft schemas.
  * live-only endpoints the request table never lists: ut/%s/squad/list,
    ut/%s/user/club, ut/%s/club/stats/*, ut/%s/clientdata/<key>. The template
    table is a floor, not a ceiling -- the log is the only ground truth.
  * 163 RS4 call names exist; we served 17. All now served.

FIXED: club/stats/* was answering with the entire 28-item club inventory on every
poll (it fell through to the generic /club route).

UNSOLVED: the pack reveal's "Send to Club" (PUT ut/%s/item) kills the FUT session
whatever we answer -- {} included -- while its sibling quick-sell endpoint accepts
a bare {}. Seven hypotheses eliminated by live test, documented in
REBUILD_RESEARCH.md S14c so none get re-walked. FUT_PACK_AUTOCLUB routes around it.
Also unfixed: store tiles render "unknown" (displayGroup is parsed RECURSIVELY by
the same element parser; sending it FROZE the store, so FUT_STORE_GROUPS=1 is
default off).

Tests: test_fut_contract.py 380 (live, read-only) + test_match_rewards.py 51 (pure).

Note: fut_store.py carries some pre-existing uncommitted changes from before this
session (pack catalogue ids, pending-pile behaviour) that could not be separated
from this session's additions in the same file.

reversed schemas so a future edit that reintroduces that class of bug fails here

never mutates the profile. Run: python3 tools/test_fut_contract.py
MOSTLY read-only: every check but one uses GET, so no pack is bought and no squad
is written. THE ONE EXCEPTION is test_club_rename_roundtrip, which PUTs a club
name to exercise the rename endpoint and RESTORES the original in a finally block.
(The docstring used to promise strictly read-only; that promise is now this
paragraph instead of a lie.)
