Replace anyhow in embedding production code with EmbeddingError, move
RetrievalStrategy into common config, and deduplicate Surreal test setup
via common::test_utils.
Relocate SurrealDB serde helpers out of storage types so they can be
reused broadly, and align retrieval-pipeline test setup with configured
embedding dimensions.
Move FlexibleIdVisitor, deserialize_flexible_id, and four datetime serde helpers
from repeating inside every macro expansion into a shared
common/src/storage/types/serde_helpers.rs module.
14 macro invocations × 6 items = ~84 fewer redundant function definitions.
Fragile cross-module imports (file_info::deserialize_flexible_id etc.)
are updated to point to the canonical module.
