Implements issue #112: MLS group state must survive process restarts. The MLS provider hardcoded an in-memory store separate from the chat store, so a restart lost every group. Fold the OpenMLS StorageProvider into libchat's own ChatStore so one durable store holds both chat state and MLS group state. - storage: ChatStore subsumes StorageProvider<CURRENT_VERSION>, so a ChatStore is the whole durable-storage contract (identity/ephemeral/conversation/ratchet sub-stores plus the MLS key-value surface). - chat-sqlite: ChatStorage implements StorageProvider over an mls_kv table (migration 003_mls_storage), a byte-faithful port of MemoryStorage with decode errors surfaced instead of unwrapped and the reference clear_proposal_queue orphan-key bug fixed. The separate SqliteMlsStorage type is removed. - conversations: MlsPqProvider becomes a transient view borrowing the shared store and a long-lived crypto backend, so the store stays singly owned; ServiceContext hands it out via mls_provider(). ExternalServices drops its ST associated type, leaving one CS. GroupV2/de_mls's thread-safe-error bound is restated on CS because an associated-type bound does not elaborate through a supertrait. - client: the store is always ChatStorage, so fix it as such and drop the vestigial store generic from ChatClient and the builder. Retire the stubbed in-memory MemStore in favour of ChatStorage::in_memory(). - GroupV1 conversations resume across a restart through the existing MlsGroup::load path, proven by a drop-and-reload integration test.
