Add a `CreatePriceObservations` instruction that registers a TWAP price-observations account for a pool over a time window, via a chained call to the configured TWAP oracle program. The pool acts as the price source: the AMM authorizes it with its pool PDA seed so the oracle ties the feed to that pool. The feed's initial tick is read from the pool's authoritative `CurrentTickAccount` (validated against its pool-derived PDA) rather than being supplied by the caller, so the feed cannot be seeded at a forged price — mirroring what `RecordTick` does. The clock is verified to be the canonical 1-block LEZ clock, and creation is rejected if the observations account already exists. To support the chained call, `AmmConfig` and the `Initialize` instruction are extended with a `twap_oracle_program_id` that the instruction reads.
