feat!: persist T-Bank data and synchronize reads

Store account membership, portfolio, operations, forecasts and market sources in SQLite. Coalesce scoped refreshes, fence connection revisions, preserve complete financial snapshots and stabilize operation period state. BREAKING CHANGE: investment reads return data/meta resource envelopes and locally persisted snapshots; consumers must use the matching OpenAPI contract and explicit synchronization endpoints.
