Enforce pause checks on base-token interop deposits

bridgehubDepositBaseToken can still execute while the router is paused because it calls _bridgehubDepositBaseToken directly and lacks whenNotPaused, unlike the non-base path (_bridgehubDeposit) which is pause-gated. In an incident-response pause, L2_INTEROP_CENTER can therefore keep processing base-token deposits, defeating the emergency stop for that asset class.

Lines 172 to 176 in b2ea9ab

	L2_LEGACY_SHARED_BRIDGE = _legacySharedBridge;
	require(address(_l1AssetRouter) != address(0), EmptyAddress());
	L1_CHAIN_ID = _l1ChainId;
	L1_ASSET_ROUTER = _l1AssetRouter;
	BASE_TOKEN_ASSET_ID = _baseTokenAssetId;

Set BRIDGE_HUB during updateL2 upgrades

updateL2 is the non-genesis upgrade path for L2AssetRouter, but it never initializes BRIDGE_HUB. Since the previous implementation stored bridgehub as an immutable (no storage slot), upgraded proxies leave this new storage field at zero, so BRIDGE_HUB() returns address(0) after upgrade and breaks backward-compatible consumers expecting the bridgehub address.
