refactor: rename functions to verb-based naming convention

Rename functions across app/assets/ to follow verb-based naming:
- is_scalar → check_is_scalar
- project_kv → expand_metadata_to_rows
- _visible_owner_clause → _build_visible_owner_clause
- _chunk_rows → _iter_row_chunks
- _at_least_one → _validate_at_least_one_field
- _tags_norm → _normalize_tags_field
- _ser_dt → _serialize_datetime
- _ser_updated → _serialize_updated_at
- _error_response → _build_error_response
- _validation_error_response → _build_validation_error_response
- file_sender → stream_file_chunks
- seed_assets_endpoint → seed_assets
- utcnow → get_utc_now
- _safe_sort_field → _validate_sort_field
- _safe_filename → _sanitize_filename
- fast_asset_file_check → check_asset_file_fast
- prefixes_for_root → get_prefixes_for_root
- blake3_hash → compute_blake3_hash
- blake3_hash_async → compute_blake3_hash_async
- _is_within → _check_is_within
- _rel → _compute_relative
