Full .ndjson import / reorganize UI with Financial Tools / Raw Data tabs (#1208)

* Reorganize import UI with Financial Tools / Raw Data tabs

Split the flat list of import sources into two tabbed sections using
DS::Tabs: "Financial Tools" (Mint, Quicken/QIF, YNAB coming soon) and
"Raw Data" (transactions, investments, accounts, categories, rules,
documents). This prepares for adding more tool-specific importers
without cluttering the list.

* Fix import controller test to account for YNAB coming soon entry

The new YNAB "coming soon" disabled entry adds a 5th aria-disabled
element to the import dialog.

* Fix system tests to click Raw Data tab before selecting import type

Transaction, trade, and account imports are now under the Raw Data tab
and need an explicit tab click before the buttons are visible.

* feat: Add bulk import for NDJSON export files

Implements an import flow that accepts the full all.ndjson file from data exports,
allowing users to restore their complete data including:
- Accounts with accountable types
- Categories with parent relationships
- Tags and merchants
- Transactions with category, merchant, and tag references
- Trades with securities
- Valuations
- Budgets and budget categories
- Rules with conditions and actions (including compound conditions)

Key changes:
- Add BulkImport model extending Import base class
- Add Family::DataImporter to handle NDJSON parsing and import logic
- Update imports controller and views to support NDJSON workflow
- Skip configuration/mapping steps for structured NDJSON imports
- Add i18n translations for bulk import UI
- Add tests for BulkImport and DataImporter

* fix: Fix category import and test query issues

- Add default lucide_icon ("shapes") for categories when not provided
- Fix valuation test to use proper ActiveRecord joins syntax

* Linter errors

* fix: Add default color for tags when not provided in import

* fix: Add default kind for transactions when not provided in import

* Fix test

* Fix tests

* Fix remaining merge conflicts from PR 766 cherry-pick

Resolve conflict markers in test fixtures and clean up BulkImport
entry in new.html.erb to use the _import_option partial consistently.
