fix(matches): close the second, unguarded match-economy authority
CI / Build, lint & test (push) Successful in 3m15s

`POST /matches/result` granted coins, XP, level-ups, statistics, four objective
metrics, loan expiry, season progression and achievements across a dozen
SEPARATE writes with no transaction and no idempotency key. Every call
re-credited the same match, and any mid-way failure half-applied it. It sat
beside `/matches/complete`, so nothing stopped one match being paid twice
through two different doors.

It cannot be made exactly-once in place: that needs a caller-supplied match
identity, and this request shape has none. Deriving one from the body would
collapse two legitimate matches with the same scoreline into one — the
under-credit trap already documented for the `fp:` fallback. So the route fails
closed: it rejects with a message naming `/matches/complete`, rather than 404,
so a caller learns why.

The behaviour it uniquely drove is kept, not deleted. `process_match` was the
ONLY caller of loan expiry and Core's season model, so both move into
`complete_match`'s transaction behind opt-in `expire_loans` / `advance_season`
flags. Both default OFF, which keeps the FIFA 17 retail path byte-identical:
FIFA 17 has its own loan and Seasons models, and Core's season END GRANTS coins
and a pack — invisible economy on a path that never asked for it. Their pooled
implementations are replaced by `expire_loans_tx` and
`season::record_match_tx`, so a loan that expires or a season that ends commits
with the match that caused it.

Notifications (level-up / objective / loan / season) were pooled side effects of
the removed path. They now emit from the route AFTER the commit — never inside
the transaction, since a failed notification must not roll back a completed
match — and only when `applied`, so a replay no longer re-notifies. The pooled
path had no replay concept and notified every time.

Also fixes a real bug this surfaced: `/auth/reset` never deleted
`match_completions`, which carries un-cascaded foreign keys to BOTH `matches`
and `profiles`. Any profile that completed a match through the authoritative
route — i.e. every FIFA 17 profile after a retail match — failed to reset with a
database error. It is now deleted first, and ordering is documented.

Tests: the 20 integration call sites move to the authoritative route through one
helper that mints a per-call identity (each call IS a distinct match). New
coverage for the closed path: it rejects without moving the balance or writing
history; Core progression stays off unless opted into; a replay does not
duplicate notifications; and a profile that completed matches can still be
reset.
