Problem

schema_create.c and schema_open.c still implement tiered: / object: / tier: create and shared-colgroup open paths after the tests that used them are gone. src/tiered stays in the tree; this ticket only strips schema call sites.

Change

Strip __create_tiered, __create_tiered_tree, and the schema_create URI dispatch that maps those prefixes onto them. Flatten or drop is_tiered_shared create/open logic in these files. Strip import .wtobj branches in schema_create. Delete __wti_schema_get_tiered_uri / __wti_schema_release_tiered from schema_list.c if create was their only caller. Creating those URIs should fail as an unexpected object type, not map to file:. Keep __wt_schema_open_storage_source (still called from src/tiered). Keep __wt_schema_tiered_shared_colgroup_name (cur_metadata.c still calls it). Do not remove WT_TIERED / WT_DHANDLE_TYPE_TIERED / bstorage header fields. Do not change tests, docs, or src/tiered. Leave table/file tiered_storage= parse stubs.

Test

Ninja Debug build. cd dist && ./s_fast. python3 ../test/suite/run.py test_schema01 from build/. Do not run test_tiered*.
