fix(db): reassign CLARIN table ownership without the public. prefix

Revert the in-place edits to V7.2_2022.07.28__Upgrade_to_Lindat_Clarin_schema.sql
and V7.6_2024.08.05__Added_Preview_Tables.sql -- both are already applied, so
changing their content breaks their Flyway checksum and every existing install
fails validation on the next startup.

Add V7.6_2026.09.11__Clarin_tables_owner_schema_agnostic.sql instead, which
restates the same `ALTER TABLE ... OWNER TO dspace` intent for the 17 CLARIN and
preview objects, resolving each name through search_path via to_regclass() rather
than a hardcoded `public.` qualifier.

The reassignment is best-effort: it is skipped when the `dspace` role is absent,
when the object is already owned by it, or when the statement lacks the required
privileges (the target role needs CREATE on the object's schema). A tenant-owned
schema therefore keeps its current owner instead of failing the migration.

Verified against PostgreSQL 15 for: non-public schema with and without the schema
grant, repeated runs, a database with no CLARIN tables, a classic public-schema
install, and a cluster with no `dspace` role. Only the search_path schema is
touched -- a same-named table in `public` is left alone.
