funman300 fb38ee6087 fifa17: claim five routes whose handlers were already unreachable
Read the client's COMPLETE UTAS route surface out of CardsDLL's .rdata in the
running process (new tools/url_template_probe.py) and probed every one against
staging, where the Python upstream is deliberately dead so anything the Rust host
does not own answers 502 instead of being silently proxied.

That found five routes whose handlers already existed and were dead code because
`classify` never produced their Route -- the same defect as `season/list` and
`watchList`, whose fix comments are still in the file. This is the third and
fourth time:

  captcha        -> handle_static_ack, which already returns the oracle's exact
                    {encodedImg,sequence,sizeBeforeEncode}
  tfa            -> handle_static_ack, {}
  livemessage    -> handle_static_ack, {}
  activeMessage  -> handle_static_ack, {}
  tournament/user-> FeatureOffEmpty, {} == the oracle with FUT_MODES off
                    (tools/utas_server.py:1504); the client builds this literal
                    at CardsDLL 0x18021e540 and the bare `tournament` arm never
                    matched it

Route's own doc comment already claimed the first four as "Rust-owned
UNCONDITIONAL", so the documentation was wrong rather than the intent. All five
are byte-identical to the oracle, so claiming them is parity, not new behaviour.
Invisible in production because the upstream answers there.

Two tests pin the vocabularies so a handler cannot go unreachable a fifth time;
both are mutation-checked (removing the captcha arm fails the first).

Also documents the surface in docs/CLIENT_ROUTE_SURFACE.md, including the trap
that bit me repeatedly: an .rdata literal is a FRAGMENT, not a callable path.
`clientdata`, `purchasegroup`, `sbs/challenges`, `squadBuildingSets`, `club/items`
and `item` all looked unserved and are not. Only `squad/mode` is genuinely
unserved, and correctly so -- it is Draft-only, which is out of scope.

L5 finding: there is NO consumable-apply route anywhere in the binary. The only
owned-item mutations the client can express are PUT item (move/pile), DELETE
item/<id> and POST delete/item (quick sell), and PUT squad. So applying a
consumable is not a dedicated endpoint; L5/L6 must be pursued by capturing the
PUT item payload, not by implementing a route that does not exist.

Host 123 lib + 45 host_test, fmt and clippy clean. tournament/user, livemessage
and activeMessage verified 200 on staging (were 502).
