db: business-layer schema — ledger/device event split, tariffs, permits, sessions

Implements the wiki design in packages/db + packages/shared. Event split: rename events -> ledger_events (signed business ledger) and add device_events (unsigned telemetry). ledger_events gains a signed JSON payload (amount/tariffVersionId/sessionRef/tender…) + keyId; canonicalize() includes the payload via sorted-key serialization so business data is tamper-evident. Raw Dingtian input now writes device_events, not a signed input_received. New tables: tariffs + immutable tariff_versions (composable/versioned, currency + FX-ready), permits (+ permit_credentials, permit_plates; maxConcurrent default 1), blocklist, sessions (rebuildable projection cache — not a source of truth). shared: split ParkingEvent/Type into LedgerEvent/LedgerEventType + DeviceEventKind; add LedgerPayload, Tender, TariffStructure/TariffBlock. Regenerated a single baseline migration (no production chain data existed). Verified: chain appends + verifyChain ok; tampering a payment payload breaks the signature. Full repo builds (5/5).
