* Add shared sync statistics collection and provider sync summary UI
- Introduced `SyncStats::Collector` concern to centralize sync statistics logic, including account, transaction, holdings, and health stats collection.
- Added collapsible `ProviderSyncSummary` component for displaying sync summaries across providers.
- Updated syncers (e.g., `LunchflowItem::Syncer`) to use the shared collector methods for consistent stats calculation.
- Added rake tasks under `dev:sync_stats` for testing and development purposes, including fake stats generation with optional issues.
- Enhanced provider-specific views to include sync summaries using the new shared component.
* Refactor `ProviderSyncSummary` to improve maintainability
- Extracted `severity_color_class` to simplify severity-to-CSS mapping.
- Replaced `holdings_label` with `holdings_label_key` for streamlined localization.
- Updated locale file to separate `found` and `processed` translations for clarity.

Breaks our Plaid sync process out into more manageable classes. Notably, this moves the sync process to a distinct, 2-step flow:
1. Import stage - we first make API calls and import Plaid data to "mirror" tables
2. Processing stage - read the raw data, apply business rules, build internal domain models and sync balances
This provides several benefits:
- Plaid syncs can now be "replayed" without fetching API data again
- Mirror tables provide better audit and debugging capabilities
- Eliminates the "all or nothing" sync behavior that is currently in place, which is brittle
