fix(config): read the HFresh multivector config, widen shard statuses, test against 1.40

[g-despot]

Fix. config.get() returned multi_vector=None for every HFresh index because the HFresh reader hardcoded it. It now parses the server's multivector block with the same helper the HNSW and flat readers use, so MUVERA settings round-trip. Verified live against 1.40.0: _MultiVectorConfig(encoding=_MuveraConfig(enabled=True, ksim=4, dprojections=16, repetitions=10)), and a plain HFresh vector still reads back None.

Typing. ShardTypes lists every status core defines (storagestate/status.go), adding LOADING, LAZY_LOADING, SHUTDOWN, UNAVAILABLE, RECOVERING. per_node_status values use it.

CI. Matrix adds 1.40.0 and bumps 1.39 to 1.39.10 and 1.38 to 1.38.20; integration, journey and pyodide jobs run on 1.40.0. Two tests needed changes for current servers: the shards test compared per_node_status keys (1.40 populates the map), and servers from 1.38.19 / 1.39.10 / 1.40.0 reject an empty alias name in a permission, so the role case that relied on "" meaning every alias is dropped (the "*" case covers the same path). The authlib dev pin now satisfies the package requirement. The embedded default moves to 1.40.0 (the integration_embedded suite passes locally and reports 1.40.0).

Tests: new parametrized reader test, a mock get_shards test, and a gated HFresh MUVERA integration test. Full integration/ on 1.40.0: 1147 passed, remaining failures are auth containers not present locally.
