Add transaction count validation for all banking providers (SimpleFIN,
Lunch Flow, and Enable Banking) during the account setup process.
This change fetches transaction data for each bank account immediately
after provider credentials are configured, allowing users to see
warnings about accounts with no transaction history before completing
the setup.
Key changes:
- SimpleFIN: Fetch accounts and check transaction counts after token setup
- Lunch Flow: Check transaction availability after API key configuration
- Enable Banking: Validate transaction data after OAuth authorization
- Display warning messages in provider panels when issues are detected
- Warnings show accounts with 0 transactions in the last 90 days
The warnings appear in the /settings/providers screen before the
"Configured and ready to use" message, giving users early visibility
into potential data availability issues.
