[Correct Owner Address] Migrate Stride to opt-in PSS

NOTE: The previous props #1012 and #1013 contained an error that will cause the execution of the change to fail. This is the replacement.

SUMMARY: Stride moves from ICS Top-N (95%) to an opt-in PoA-style model with 7 equal-weight validators, and control of ICS config shifts from Hub governance to a Stride Association multisig. Fees will pay those 7 validators directly.

Why

• ICS is being sunset (planned 2026) and doesn't cover validator costs.
• Current flow sends revenue to stakers; validator commissions are negligible.

What changes (Hub)

• Submit MsgUpdateConsumer to:
  • Set new owner = Stride Association multisig.
  • topN: 0 (opt-in), validatorSetCap: 7, validatorsPowerCap: 1.
  • Allowlist the 7 validators.

Validators (7)

• Imperator, Polkachu, Stakecito, Keplr, Cosmostation, Lavender.Five, Citadel.One.

Follow-on (Stride)

• Redistribution 85% → 100%.
• Pay fees directly to the 7 validators' fee addresses.
