Josh Creek 3817df2a12 feat(multiplayer): wire structured event logging into server routes
server/observability existed fully unit-tested but was imported by
nothing outside its own package -- no HTTP handler ever called it, so
its credential redaction protected zero real log output. Wire it into
Service via an optional Log field (nil-safe, so every existing Service
literal keeps compiling unchanged) and call it from the two
workload-authenticated server routes -- register and result -- at
every outcome: unauthorized, rejected, conflict and success. Wire
cmd/control-plane to actually emit those events as JSON lines on
stderr.

Add a secret canary test that drives both routes end to end with
realistic bearer-token and result-nonce values and asserts neither
literal secret appears anywhere in what Service.Log actually received
-- a stronger claim than the existing observability unit test, which
only proves redact() strips a synthetic value under a denylisted key
name. redact() is still key-name-based, not content-based: a future
call site that logs a secret under an unlisted key name would not be
caught by this test or by redact() itself, only by the same discipline
applied here of never putting raw request/token bytes into Fields.

Queue, proposal and assignment mutation routes are not wired yet.
