Wire the Tleilaxu Ambassador force return

The last unimplemented Ambassador effect is now reachable. A placed Tleilaxu
token gives its beneficiary — the Ecaz owner or its ally — a private
ecazAmbassador decision at the new revival stage: one to four physical counters
return from the Tanks to reserves at zero cost, quoted by the existing
game/tleilaxu-ambassador-forces.ts, which also enforces the shared
Fedaykin/Sardaukar one-per-turn counter and keeps Ixian cyborgs uncapped.

The player view projects the maximum, Tanks and elite inventory and current
elite usage to the beneficiary only; the entry control offers a per-count
button and an explicit "Return no forces" decline; all four AI profiles choose
a legal return from the decision owner's own view or decline when the Tanks are
empty. Player-facing coverage text now lists Tleilaxu.

Kept gated exactly as recorded: the printed leader alternative, ordinary
force/free/leader allowance accounting around this independent grant,
dead-twice eligibility, and Tleilaxu free-income repeat scope. No ordinary
revival allowance, price, phase or income path changes.

Evidence: tests/tleilaxu-ambassador-engine.test.ts drives a genuine arrival into
a placed token and asserts the beneficiary-only projection, the typed return
with unchanged spice, the shared elite limit, malformed/over-maximum rejection
with immutability, the ordinary-only return, the decline path and the rendered
control. The four-profile ecaz-entry-bots loop now covers tleilaxu, and the
former unsupported-effect and copy-list pins were updated to the supported
behaviour rather than re-pinned. Offline suite 7,797/7,797 with typecheck and
lint clean. No game, seat, saved state or deployment changes.
