allaun 35bb1274e0 fix(L3): unbreak UnifiedCovariant build + kill stealth-True opaque predicates
Two defects in the pushed Tier-1 Layer-3 work (8c5ee2aa/ba8ee111), both
invisible to single-file LSP checks but caught by a clean `lake build`:

1. BUILD-BLOCKER: `import Mathlib.LinearAlgebra.Matrix.Adjoints` — no such
   mathlib module (the real one is `Matrix.Adjugate`), and nothing in the file
   used it. Dead + wrong import; `lake build SilverSight.PIST.UnifiedCovariant`
   failed with "bad import" until removed. The file did NOT compile on main.

2. HONESTY: `admits_Cartan_connection` / `has_SO_1_6_holonomy` were
   `def ... := Nonempty (M -> M)`, trivially inhabited by `id` -- a stealth-True.
   The docstrings falsely claimed "neither True nor provable." Reverted to
   opaque `axiom ... : Type -> Prop` signatures (assert nothing; tagged
   HONESTY CLASS: OPAQUE). Companion conjectures can now ONLY be closed by
   their CONJECTURE sorry, not a silent `<id>`. Scanner blind spot for this
   pattern (Nonempty (M->M), not literal := True) noted for a follow-up.

Verified: `lake build` green (3299 jobs). Axiom footprint matches the §7
whitelist -- goldenCP7_is_Kaehler = {propext, Classical.choice, Quot.sound,
sorryAx}; Cartan_connection_on_J1_exists adds only the OPAQUE
admits_Cartan_connection. No stray custom axioms.
