* refactor(cli): extract generic tree picker from Notion-specific modules
Rename notion-page-picker-tree → tree-picker-state and
notion-page-picker-tui → tree-picker-tui, removing Notion-specific
naming so the tree picker can be reused for database scope selection.
Update notion-page-picker to consume the new generic interfaces.

* feat(cli): add database tree picker for schema and table scope selection
Replace inline multiselect prompts in setup-databases with a new
database-tree-picker that uses the generic tree picker TUI. This gives
database scope selection the same grouped tree UI as the Notion page
picker, combining schema and table selection into a single step.
