fix(ci): the storage layer names only SDK suites that exist

[cryptskii]

Why

#1069 changes only the storage node, so the layer selector runs the sdk-node-protocol group. That group failed:

error: no test target named `b0x_integration` in `dsm_sdk` package

The group named four SDK suites that no longer exist. #1069 is the first storage-only PR since they were deleted, so nothing had run the group until now.

Name	Kind	Deleted in	Effect
b0x_integration	integration target	#977	cargo refuses: the group fails
storage_full_lifecycle	integration target	#932	cargo refuses: the group fails
sdk::storage_sync_sdk	lib filter	#976	matches nothing, runs nothing, passes
sdk::storage_node_health	lib filter	#977	matches nothing, runs nothing, passes

What

• The four names are removed from ci/layers.toml.
• No SDK integration binary exercises the storage-node contract now, so the group runs one command: the four lib suites that do (handlers::storage_routes, sdk::storage_node_sdk, sdk::b0x_sdk, sdk::storage_set). On test(storage): the object store's refusals are exercised #1069 these ran and passed 48 tests; the stale filters added none.
• ci/select_layers.py no longer renders an integration-target list.
• A new selector self-test, test_every_named_sdk_suite_is_a_module_that_exists, refuses a lib filter that does not resolve to a module of dsm_sdk. That makes the silent case loud.

Evidence

• python3 ci/test_select_layers.py: 17 tests, OK.
• Mutation control: sdk::storage_sync_sdk put back into lib_filters makes the new test fail with "sdk::storage_sync_sdk names no module of dsm_sdk". Restored.
• Rendered for test(storage): the object store's refusals are exercised #1069's diff: changed ['STORAGE'] → ['SDK_NODE_PROTOCOL', 'STORAGE'], and sdk-node-protocol runs the single lib command above.

Editing ci/** is a FULL trigger, so this PR runs the full matrix. #1069, rebased after this merges, becomes the first live run of the narrow storage path.

Not changed

Which SDK suites a storage change should escalate to is unchanged apart from the dead names. The node-backed SDK lib suites (handlers::node_e2e_tests and the admission and faucet tests, which stand up real nodes) are not in the group. Adding them is a coverage decision for the owner.
