Adds StepByStepPanel component to SourceConnectFlow that renders numbered
setup steps with optional links and input fields for each connector. Wires
it as the primary panel for any connector with steps defined, with existing
OAuth/Local/Filesystem panels as fallbacks. Also updates connectors.ts to
use ConnectorMeta (with SetupStep/inputFields) as the canonical type and
exports SourceCard as a backward-compatible alias.

SetupWizard orchestrates the pick→connect→ingest→ready state machine with a
step indicator; SetupScreen now transitions to the wizard after all boot checks
pass (phase === 'ready') instead of immediately calling onReady().

SourcePicker renders a grouped card grid for selecting data sources; SourceConnectFlow
provides per-source auth panels (OAuth, filesystem, local); IngestDashboard polls sync
status every 2s with progress bars; ReadyScreen shows a celebration screen with
context-aware starter queries.
