r4bbit 0e2c5f9329 feat(amm): refresh TWAP current tick on every reserve-mutating instruction ...

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.
