Robin Braumann d292ca54ea refactor(core): Replace agent knowledge base binary data storage with blob storage (no-changelog) 
Moves agent knowledge file bytes off BinaryDataService (N8N_DEFAULT_BINARY_DATA_MODE)
onto the @n8n/blob-storage ByteStore backends already used for agent execution logs,
governed by N8N_EXECUTION_DATA_STORAGE_MODE. Falls back to the local filesystem when
that mode is 'database', since no db-backed byte store exists.

Existing knowledge-file rows are deleted by the migration rather than migrated, as
the feature is at low rollout.
