Make swap_exact_input, swap_exact_output, add_liquidity, remove_liquidity, and sync_reserves keep the pool's TWAP current tick in sync with its reserves. Each now takes the current-tick and clock accounts, reads the TWAP program ID from the config account, validates the clock account and the current-tick PDA, and after computing the post-op pool chains an UpdateCurrentTick to the oracle carrying the post-op spot price, with the pool passed as the authorized price source via its pool PDA seed. sync_reserves additionally now takes the config account so it can resolve the TWAP program ID and gate on initialization, consistent with the other instructions. The invariant current_tick == tick(reserves) therefore holds after every operation. Proportional add/remove preserve the price, so the tick is unchanged for them, but the refresh still runs and lands on the correct value.
