fix(inspector): cockpit-wide audit — Unknown routing, time fmt, loading pill, +5 more

Closes the seven-bug list surfaced by the user's screenshot of a live
session where every metric stayed at zero:

1. Event::Unknown now routes through state::apply via apply_unknown(),
   which inspects extra["type"] and dispatches to the same per-plugin /
   per-metric updates typed variants get. Lifecycle events
   (lifecycle.<phase>) refresh session.current_phase. Plugin events
   (crow.trust.scored, djinn.anchor.set, pech.ledger.appended,
   hydra.veto.fired, sylph.destructive.veto, ...) bump calls,
   last_event, display_value.
2. fmt_event_time(t, baseline): detects Unix epoch via t >= 1e9 and
   formats relative to a baseline (min epoch in the ring buffer or
   started_at fallback) as MM:SS.sss / H:MM:SS. The events table no
   longer shows truncated absolute timestamps.
3. Loading pill in the top bar: "waiting for runtime…" with 1/2/3-dot
   pulse when events.is_empty() && !demo_mode, dropped on first event.
4. tracing_log_size_kb -> tracing_log_size_bytes; new fmt_log_size
   B/KB/MB/GB ladder. The 34 GB display was a double-divide-by-1024 bug.
5. synthesize_health caps cpu_pct at 80% (TODO: real tokio metrics).
6. Phase pipeline current-phase highlight was already correct — it was
   transitively broken because current_phase wasn't being set; Fix 1
   resolves it.
7. Plugins last_seen consistency follows from Fix 1.

Also updates the schema tests (src + tests) to match the v0.6 schema
relaxation: well-typed branches stay strict, but missing-required and
unknown-discriminator now fall through to genericVariant rather than
rejecting. Tests rewritten to assert the new semantics.

80 Rust tests pass / 0 fail across all binaries.
