CB-606: refuse an unrecognized auth.mode, per-profile placement, or top-level placement policy at config load

An auth.mode typo (e.g. "toekn") used to silently fall back to loopback-trust with no signal
anywhere — validateAuthExposure() only checks the pairing on a non-loopback bind, so on the
common loopback bind the daemon started cleanly and authenticated nobody. Per-profile placement
had the same shape, falling back to legacy pane placement. The top-level placement policy name
was already validated by PlacementPolicies.fromName, but only lazily at first spawn through
CompositePeerLauncher's Supplier; it is now checked eagerly at load, calling fromName itself as
the single source of truth.

+#
+# `weighted` IS NOT "cheapest first" — read this before you set weights (CB-589).
+# It is smooth weighted round-robin: it spreads spawns across EVERY profile that has a free slot,
+# in weight ratio. It has no idea which profile costs money. So with local:10 / paid:2 you do not
+# get "use local, overflow to paid" — you get roughly one spawn in six going to the paid profile
+# while the local box still has a free slot.
+#
+# There is a sharper second effect. The policy's running score map lives for the daemon's whole
+# life. While a profile is at maxLoad it is filtered out and its score FREEZES, so the paid
+# profiles keep accumulating against it. When the local slot frees up it returns with a stale
+# score and can LOSE the next pick — a paid spawn while the free box sits idle.
+#
+# Until a real cost-first policy exists, the workaround is to make the ratio decisive rather than
+# proportional: give the free profile a weight so large that it wins every pick it is eligible
+# for, and paid profiles only ever take genuine overflow. On this host that is local weight 100
+# against paid weights of ~1.
+#
+# The gotcha with that workaround: it expresses a PREFERENCE ORDER through a RATIO knob. Add a
+# future profile at weight 150 and it silently outranks the free box, with nothing to warn you.
