fix: _isPriceStable fallback interval can still revert on pools with very short history (#610)

Browse source 
Wrap the fallback pool.observe() call in a try/catch so that pools with
insufficient observation history for both the primary (30s) and fallback
(6000s) intervals return false (price unstable) instead of reverting with
an opaque Uniswap V3 error. This prevents recenter() from failing for
unpermissioned callers on newly created pools.
